CVSS v3.1 |
| open-computer-use through commit 610bac8 contains a stored cross-site scripting vulnerability in Logger.write_log_file in os_computer_use/logging.py, which writes transcript text into log.html without HTML escaping. Attackers controlling sandbox content, such as web pages or files appearing in run_command output, can inject script that runs when operators open the log, exfiltrating transcript contents. |
| Agnaistic agnai through 1.0.555 contains a hard-coded credentials vulnerability in self-host.docker-compose.yml, which sets a fixed admin password and public JWT secret. Unauthenticated attackers can log in as admin or sign their own JWT with admin: true to impersonate users, reset passwords, and change server configuration. |

nvme-multipath: fix flex array size in struct nvme_ns_head
struct nvme_ns_head contains a flexible array member, current_path[],
which is indexed using the NUMA node ID:
head->current_path[numa_node_id()]
The structure is currently allocated as:
size = sizeof(struct nvme_ns_head) +
(num_possible_nodes() * sizeof(struct nvme_ns *));
head = kzalloc(size, GFP_KERNEL);
This allocation assumes that NUMA node IDs are sequential and densely
packed from 0 .. num_possible_nodes() - 1. While this assumption holds
on many systems, it is not always true on some architectures such as
powerpc.
On some powerpc systems, NUMA node IDs can be sparse. For example:
NUMA:
NUMA node(s): 6
NUMA node0 CPU(s): 80-159
NUMA node8 CPU(s): 0-79
NUMA node252 CPU(s):
NUMA node253 CPU(s):
NUMA node254 CPU(s):
NUMA node255 CPU(s):
That is, the possible/online NUMA node IDs are: 0, 8, 252, 253, 254, 255
In this case: num_possible_nodes() = 6
So memory is allocated for only 6 entries in current_path[]. However,
the array is later indexed using the actual NUMA node ID. As a result,
accesses such as:
head->current_path[8] or
head->current_path[252]
goes out of bounds, leading to the following KASAN splat:

==================================================================
Fix this by allocating the flexible array using nr_node_ids instead
of num_possible_nodes(). Since nr_node_ids represents the maximum
possible NUMA node IDs, indexing current_path[] using numa_node_id()
becomes safe even on systems with sparse node IDs. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: reset read_slot when reusing r10bio for discard
put_all_bios() always drops devs[i].bio, but it only drops
devs[i].repl_bio when r10_bio->read_slot < 0. If discard reuses an
r10bio that was previously used for a read, read_slot can still be
non-negative, and discard cleanup can skip bio_put() on repl_bio.
Reset read_slot to -1 when preparing an r10bio for discard so the
replacement bio is always released correctly. |
| In the Linux kernel, the following vulnerability has been resolved:
ocfs2: reject FITRIM ranges shorter than a cluster
ocfs2_trim_mainbm() trims the global bitmap in cluster units, but its
too-short range validation only checks sb->s_blocksize.
On filesystems with a cluster size larger than the block size, a FITRIM
range that is at least one block but shorter than one cluster is accepted
and shifted down to len == 0. The later start + len - 1 and len -= ...
arithmetic then underflows and can drive trimming past the requested
range.
Reject ranges shorter than s_clustersize instead. That preserves the
existing -EINVAL behavior for requests that cannot discard even one
allocation unit and keeps zero-cluster trims out of the group walk. |

wifi: mt76: mt7996: Fix possible token leak in mt7996_tx_prepare_skb()
If link_conf or link_sta lookup fails in mt7996_tx_prepare_skb routine,
mt7996 driver leaks an already allocated tx token. Fix the issue
releasing the token in case of error. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Handle layout stid in nfsd4_drop_revoked_stid()
nfsd4_drop_revoked_stid() has no SC_TYPE_LAYOUT case, so when a
client sends FREE_STATEID for an admin-revoked layout stid, the
default branch releases cl_lock and returns without unhashing or
releasing the stid. The stid remains in the IDR and on the
per-client list until the client is destroyed.
Remove the layout stid from the per-client list and call
nfs4_put_stid() to drop the creation reference. When the
refcount reaches zero, nfsd4_free_layout_stateid() handles the
remaining cleanup: cancelling the fence worker, removing from
the per-file list, and freeing the slab object. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Cancel special fields on map value recycle
Map update and delete paths currently call bpf_obj_free_fields() when a
value is being replaced or recycled. That makes field destruction depend
on the context of the update/delete operation. For tracing programs this
can include NMI context, where referenced kptr destructors, uptr
unpinning, and graph root destruction are not generally safe.
Introduce bpf_obj_cancel_fields() for the reusable-value path. It only
performs NMI-safe cleanup for timer, workqueue, and task_work fields.
Fields that need full destruction are left attached to the recycled value
and are destroyed by the final cleanup path instead.
Switch array and hashtab update/delete/recycle paths to this cancel
helper. Keep bpf_obj_free_fields() for final map destruction and for
bpf_mem_alloc destructors. Preallocated hashtabs do not have allocator
destructors, so teardown continues to walk the normal and extra elements
and fully destroy their fields.
This deliberately relaxes the eager-free semantics of map update/delete
for special fields. Programs that relied on a recycled map slot becoming
empty immediately after update/delete were relying on behavior that
cannot be implemented safely from every BPF execution context without
offloading arbitrary destructors.
There is a chance this change breaks programs making assumptions
regarding the eager freeing of fields. If so, we can relax semantics to
cancellation only when irqs_disabled() is true in the future. However,
theoretically, map values that get reused eagerly already have weaker
guarantees as parallel users can recreate freed fields before the new
element becomes visible again. |
| In the Linux kernel, the following vulnerability has been resolved:
vhost/vdpa: validate virtqueue index in mmap and fault paths
vhost_vdpa_mmap() and vhost_vdpa_fault() use vma->vm_pgoff as a
virtqueue index for get_vq_notification(), but they do not validate
that the index is smaller than v->nvqs.
The ioctl path already performs both a bounds check and
array_index_nospec(), but the mmap/fault path only checks that the
index fits in u16. This allows an out-of-range queue index to reach
driver-specific get_vq_notification() callbacks.
Fix this by extracting a unified vhost_vdpa_get_vq_notification()
helper that validates the queue index against v->nvqs and applies
array_index_nospec() before calling the driver callback. Both the
mmap and fault paths use this helper, and the bounds checking is
consolidated into a single location.
From source inspection, the most defensible impact is out-of-bounds
access in the callback path, potentially leading to invalid PFN
remaps and crash/DoS. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci: validate codec capability element length
Read Local Codec Capabilities returns a sequence of capability elements.
Each element starts with a one-byte length followed by that many payload
bytes.
hci_read_codec_capabilities() checks that the skb contains the length
byte, but then validates only caps->len against the remaining skb
length. A malformed controller response with one remaining byte and
caps->len set to one passes that check even though the element needs two
bytes. The parser then records a two-byte capability and copies one
byte beyond the advertised response payload into the codec list.
Validate the full element size, including the length byte, before adding
it to the accumulated capability length. This preserves all well-formed
capability elements and drops only truncated controller responses. |

RDMA/mlx5: Release the HW‑provided UAR index rather than the SW one
Free the UAR index returned by the hardware. |
| In the Linux kernel, the following vulnerability has been resolved:
net: fib_rules: Don't dump dying fib_rule in fib_rules_dump().
rocker_router_fib_event() calls fib_rule_get() during RCU dump.
If the fib_rule is dying, refcount_inc() will complain about it.
Let's call refcount_inc_not_zero() in fib_rules_dump(). |
| In the Linux kernel, the following vulnerability has been resolved:
tipc: reject inverted service ranges from peer bindings
tipc_update_nametbl() inserts a binding advertised by a peer node using
the lower and upper service-range bounds taken directly from the wire,
without checking that lower <= upper. The local bind path validates the
ordering (tipc_uaddr_valid()), but the name-distribution path does not.
A binding with lower > upper is inserted at the far end of the
service-range rbtree (keyed on lower) where no lookup or withdrawal can
ever match it (service_range_foreach_match() requires sr->lower <= end).
The publication, its service_range node and the augmented rbtree entry
are then leaked for the lifetime of the namespace, and there is no
per-peer cap equivalent to TIPC_MAX_PUBL on locally created bindings.
Reject inverted ranges in the network path as well. A peer node can
otherwise leak unbounded binding-table memory by sending PUBLICATION
items with lower > upper. |

crypto: cavium/cpt - fix DMA cleanup using wrong loop index
The sg_cleanup error path used list[i] instead of list[j] when unmapping
DMA buffers, leaking successfully mapped entries and repeatedly unmapping
the failed one. |
| In the Linux kernel, the following vulnerability has been resolved:
xprtrdma: Repost Receive buffers for malformed replies
rpcrdma_wc_receive() decrements the transport's Receive count for
every completion before it dispatches a successful Receive to
rpcrdma_reply_handler(). The handler must post a replacement
Receive WR before returning unless ownership of the rep has moved
elsewhere, as on the backchannel path.
Commit 2ae50ad68cd7 ("xprtrdma: Close window between waking RPC
senders and posting Receives") moved the Receive refill out of
rpcrdma_wc_receive(), where it had run ahead of every reply, into
rpcrdma_reply_handler() so that the responder's credit grant could
be parsed before reposting. The bad-version and short-reply exits
never reach that refill: they recycle the rep and return without
calling rpcrdma_post_recvs().
A remote peer can therefore drain the client's posted Receive
queue by sending a sustained stream of replies that are shorter
than the fixed transport header or that carry an unrecognized
RPC/RDMA version. Each such reply consumes one posted Receive
without replacing it. Once the queue empties, the peer's next
Send finds no posted Receive and the transport stalls until
reconnect.
Route both malformed-reply exits through the shared repost tail
after recycling the rep, refilling against buf->rb_credits, the
most recent accepted credit grant. Neither exit updates the
congestion window, so RPCs admitted under the previous grant
remain in flight awaiting replies. A smaller refill target would
let a stream of malformed replies ratchet the posted Receive count
down to the batch floor while the congestion window still admits
rb_credits RPCs; a burst of valid replies to those RPCs could then
overrun the posted Receives, and because the client connects with
rnr_retry_count of zero, a single RNR NAK terminates the
connection. Refilling against rb_credits also restores the target
that applied to malformed replies before commit 2ae50ad68cd7
("xprtrdma: Close window between waking RPC senders and posting
Receives") when rpcrdma_post_recvs() computed it from rb_credits
internally. rb_credits is at least one from connection
establishment onward, so the repost path always keeps Receives
posted. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix effective prog array index with BPF_F_PREORDER
replace_effective_prog() and purge_effective_progs() located the slot in
the effective array by walking the program hlist and counting entries
linearly. That count does not match the array layout: compute_effective_
progs() places BPF_F_PREORDER programs at the front (ancestor cgroup
first, attach order within a cgroup) and the rest after them (descendant
cgroup first). So when a preorder program is present, the linear hlist
position no longer equals the program's index in the effective array.
For replace_effective_prog() (bpf_link_update()) this overwrote the
wrong slot, corrupting the effective order. For purge_effective_progs(),
it could dummy out a slot belonging to a different program and leave the
detached program in the array while bpf_prog_put() drops its reference,
i.e. a use-after-free.
Fix both by replaying compute_effective_progs()'s placement (including
the per-cgroup preorder reversal) in a shared effective_prog_pos()
helper. Identify the entry by its struct bpf_prog_list pointer rather
than by (prog, link) value, so the lookup resolves to exactly the
attachment the syscall selected even when the same bpf_prog is attached
to several cgroups in the hierarchy. |

ice: fix FDIR CTRL VSI resource leak in ice_reset_all_vfs()
Resetting all VFs causes resource leak on VFs with FDIR filters
enabled as CTRL VSIs are only invalidated and not freed. Fix by using
ice_vf_ctrl_vsi_release() instead of ice_vf_ctrl_invalidate_vsi() which
aligns behavior with the ice_reset_vf() function.
Reproduction:
echo 1 > /sys/class/net/$pf/device/sriov_numvfs
ethtool -N $vf flow-type ether proto 0x9000 action 0
echo 1 > /sys/class/net/$pf/device/reset |
| In the Linux kernel, the following vulnerability has been resolved:
net: mvneta: re-enable percpu interrupt on resume
On Marvell MPIC platforms (Armada 370/XP/38x), mvneta uses a percpu
IRQ disable/enable scheme for NAPI: the ISR (mvneta_percpu_isr) calls
disable_percpu_irq() to mask the MPIC per-CPU interrupt and schedules
NAPI poll, which calls enable_percpu_irq() on completion to unmask.
If suspend occurs while NAPI poll is pending (between
disable_percpu_irq in the ISR and enable_percpu_irq in poll
completion), the interrupt is never re-enabled:
1. mvneta_percpu_isr: disable_percpu_irq() + napi_schedule()
=> MPIC masked, percpu_enabled cpumask bit cleared
2. NAPI poll does not complete before suspend proceeds
(on PREEMPT_RT this is highly likely since softirqs run in
ksoftirqd which gets frozen; on non-RT it can happen when
softirq processing is deferred to ksoftirqd)
3. mvneta_stop_dev => napi_disable(): cancels the pending poll
without executing the completion path
4. suspend_device_irqs => IRQCHIP_MASK_ON_SUSPEND: masks MPIC
(already masked, but records IRQS_SUSPENDED)
5. Resume: mpic_resume checks irq_percpu_is_enabled() => false
(bit was cleared in step 1) => skips unmask
6. mvneta_start_dev only restores device-level INTR_NEW_MASK,
does not touch the MPIC per-CPU mask
Result: MPIC per-CPU interrupt stays masked permanently. The NIC
generates interrupts (INTR_NEW_CAUSE != 0) but the CPU never
receives them, causing complete loss of network connectivity.
Fix by calling on_each_cpu(mvneta_percpu_enable) in the resume path
to unconditionally unmask the MPIC per-CPU interrupt regardless of
pre-suspend state. |
| In the Linux kernel, the following vulnerability has been resolved:
afs: Fix the volume AFS_VOLUME_RM_TREE is set on
Fix afs_insert_volume_into_cell() to set AFS_VOLUME_RM_TREE on the volume
replaced, not the new volume, as it's now removed from the cell's volume
tree. This will cause the old volume to be removed from the tree twice and
the new volume never to be removed. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: fix malformed ISO_END/CONT handling
Core specification (Part C vol 4 sec 5.4.5) does not exclude empty
ISO_CONT, ISO_END packets. We currently reject them if they are last.
If controller sends malformed sequence
ISO_START -> rx_len = 4, ISO_CONT skb->len 4, ISO_START
that ends payload in ISO_CONT, we leak conn->rx_skb. If controller sends
too long ISO_END, we panic on skb_put. If controller sends too short
ISO_END we accept it.
Fix by marking unfinished ISO_START via conn->rx_skb != NULL. Check
skb->len properly before skb_put. Combine the ISO_CONT/END code paths
as they require the same initial checks. Reject too short ISO_END
packets. |
