| CVE-2026-23031 | 1 Linux | 1 Linux Kernel | 2026-06-02 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak In gs_can_open(), the URBs for USB-in transfers are allocated, added to the parent->rx_submitted anchor and submitted. In the complete callback gs_usb_receive_bulk_callback(), the URB is processed and resubmitted. In gs_can_close() the URBs are freed by calling usb_kill_anchored_urbs(parent->rx_submitted). However, this does not take into account that the USB framework unanchors the URB before the complete function is called. This means that once an in-URB has been completed, it is no longer anchored and is ultimately not released in gs_can_close(). Fix the memory leak by anchoring the URB in the gs_usb_receive_bulk_callback() to the parent->rx_submitted anchor. | ||||

| In the Linux kernel, the following vulnerability has been resolved: dmaengine: lpc18xx-dmamux: fix device leak on route allocation Make sure to drop the reference taken when looking up the DMA mux platform device during route allocation. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference. | ||||

| CVE-2026-46109 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: usb: ulpi: fix memory leak on ulpi_register() error paths Commit 01af542392b5 ("usb: ulpi: fix double free in ulpi_register_interface() error path") removed kfree(ulpi) from ulpi_register_interface() to fix a double-free when device_register() fails. But when ulpi_of_register() or ulpi_read_id() fail before device_register() is called, the ulpi allocation is leaked. Add kfree(ulpi) on both error paths to properly clean up the allocation. | ||||
| CVE-2026-46075 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-sha204a - Fix potential UAF and memory leak in remove path Unregister the hwrng to prevent new ->read() calls and flush the Atmel I2C workqueue before teardown to prevent a potential UAF if a queued callback runs while the device is being removed. Drop the early return to ensure sysfs entries are removed and ->hwrng.priv is freed, preventing a memory leak. | ||||
| CVE-2026-43105 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fix memory leak of BO array in hang state The hang state's BO array is allocated separately with kzalloc() in vc4_save_hang_state() but never freed in vc4_free_hang_state(). Add the missing kfree() for the BO array before freeing the hang state struct. | ||||
| CVE-2026-43104 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Fix a memory leak in hang state error path When vc4_save_hang_state() encounters an early return condition, it returns without freeing the previously allocated `kernel_state`, leaking memory. Add the missing kfree() calls by consolidating the early return paths into a single place. | ||||
| CVE-2026-31616 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_phonet: fix skb frags[] overflow in pn_rx_complete() A broken/bored/mean USB host can overflow the skb_shared_info->frags[] array on a Linux gadget exposing a Phonet function by sending an unbounded sequence of full-page OUT transfers. pn_rx_complete() finalizes the skb only when req->actual < req->length, where req->length is set to PAGE_SIZE by the gadget. If the host always sends exactly PAGE_SIZE bytes per transfer, fp->rx.skb will never be reset and each completion will add another fragment via skb_add_rx_frag(). Once nr_frags exceeds MAX_SKB_FRAGS (default 17), subsequent frag stores overwrite memory adjacent to the shinfo on the heap. Drop the skb and account a length error when the frag limit is reached, matching the fix applied in t7xx by commit f0813bcd2d9d ("net: wwan: t7xx: fix potential skb->frags overflow in RX path"). | ||||
| CVE-2026-31585 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: media: vidtv: fix nfeeds state corruption on start_streaming failure syzbot reported a memory leak in vidtv_psi_service_desc_init [1]. When vidtv_start_streaming() fails inside vidtv_start_feed(), the nfeeds counter is left incremented even though no feed was actually started. This corrupts the driver state: subsequent start_feed calls see nfeeds > 1 and skip starting the mux, while stop_feed calls eventually try to stop a non-existent stream. This state corruption can also lead to memory leaks, since the mux and channel resources may be partially allocated during a failed start_streaming but never cleaned up, as the stop path finds dvb->streaming == false and returns early. Fix by decrementing nfeeds back when start_streaming fails, keeping the counter in sync with the actual number of active feeds. [1] BUG: memory leak unreferenced object 0xffff888145b50820 (size 32): comm "syz.0.17", pid 6068, jiffies 4294944486 backtrace (crc 90a0c7d4): vidtv_psi_service_desc_init+0x74/0x1b0 drivers/media/test-drivers/vidtv/vidtv_psi.c:288 vidtv_channel_s302m_init+0xb1/0x2a0 drivers/media/test-drivers/vidtv/vidtv_channel.c:83 vidtv_channels_init+0x1b/0x40 drivers/media/test-drivers/vidtv/vidtv_channel.c:524 vidtv_mux_init+0x516/0xbe0 drivers/media/test-drivers/vidtv/vidtv_mux.c:518 vidtv_start_streaming drivers/media/test-drivers/vidtv/vidtv_bridge.c:194 [inline] vidtv_start_feed+0x33e/0x4d0 drivers/media/test-drivers/vidtv/vidtv_bridge.c:239 | ||||
| CVE-2022-49183 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net/sched: act_ct: fix ref leak when switching zones When switching zones or network namespaces without doing a ct clear in between, it is now leaking a reference to the old ct entry. That's because tcf_ct_skb_nfct_cached() returns false and tcf_ct_flow_table_lookup() may simply overwrite it. The fix is to, as the ct entry is not reusable, free it already at tcf_ct_skb_nfct_cached(). | ||||
| CVE-2022-49135 | 1 Linux | 1 Linux Kernel | 2026-06-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix memory leak [why] Resource release is needed on the error handling path to prevent memory leak. [how] Fix this by adding kfree on the error handling path. | ||||
| CVE-2026-43069 | 1 Linux | 1 Linux Kernel | 2026-05-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_ll: Fix firmware leak on error path Smatch reports: drivers/bluetooth/hci_ll.c:587 download_firmware() warn: 'fw' from request_firmware() not released on lines: 544. In download_firmware(), if request_firmware() succeeds but the returned firmware content is invalid (no data or zero size), the function returns without releasing the firmware, resulting in a resource leak. Fix this by calling release_firmware() before returning when request_firmware() succeeded but the firmware content is invalid. | ||||
| CVE-2026-43066 | 1 Linux | 1 Linux Kernel | 2026-05-29 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ext4: fix iloc.bh leak in ext4_fc_replay_inode() error paths During code review, Joseph found that ext4_fc_replay_inode() calls ext4_get_fc_inode_loc() to get the inode location, which holds a reference to iloc.bh that must be released via brelse(). However, several error paths jump to the 'out' label without releasing iloc.bh: - ext4_handle_dirty_metadata() failure - sync_dirty_buffer() failure - ext4_mark_inode_used() failure - ext4_iget() failure Fix this by introducing an 'out_brelse' label placed just before the existing 'out' label to ensure iloc.bh is always released. Additionally, make ext4_fc_replay_inode() propagate errors properly instead of always returning 0. | ||||

| In the Linux kernel, the following vulnerability has been resolved: powerpc/xive: fix kmemleak caused by incorrect chip_data lookup The kmemleak reports the following memory leak: Unreferenced object 0xc0000002a7fbc640 (size 64): comm "kworker/8:1", pid 540, jiffies 4294937872 hex dump (first 32 bytes): 01 00 00 00 00 00 00 00 00 00 09 04 00 04 00 00 ................ 00 00 a7 81 00 00 0a c0 00 00 08 04 00 04 00 00 ................ backtrace (crc 177d48f6): __kmalloc_cache_noprof+0x520/0x730 xive_irq_alloc_data.constprop.0+0x40/0xe0 xive_irq_domain_alloc+0xd0/0x1b0 irq_domain_alloc_irqs_parent+0x44/0x6c pseries_irq_domain_alloc+0x1cc/0x354 irq_domain_alloc_irqs_parent+0x44/0x6c msi_domain_alloc+0xb0/0x220 irq_domain_alloc_irqs_locked+0x138/0x4d0 __irq_domain_alloc_irqs+0x8c/0xfc __msi_domain_alloc_irqs+0x214/0x4d8 msi_domain_alloc_irqs_all_locked+0x70/0xf8 pci_msi_setup_msi_irqs+0x60/0x78 __pci_enable_msix_range+0x54c/0x98c pci_alloc_irq_vectors_affinity+0x16c/0x1d4 nvme_pci_enable+0xac/0x9c0 [nvme] nvme_probe+0x340/0x764 [nvme] This occurs when allocating MSI-X vectors for an NVMe device. During allocation the XIVE code creates a struct xive_irq_data and stores it in irq_data->chip_data. When the MSI-X irqdomain is later freed, xive_irq_free_data() is responsible for retrieving this structure and freeing it. However, after commit cc0cc23babc9 ("powerpc/xive: Untangle xive from child interrupt controller drivers"), xive_irq_free_data() retrieves the chip_data using irq_get_chip_data(), which looks up the data through the child domain. This is incorrect because the XIVE-specific irq data is associated with the XIVE (parent) domain. As a result the lookup fails and the allocated struct xive_irq_data is never freed, leading to the kmemleak report shown above. Fix this by retrieving the irq_data from the correct domain using irq_domain_get_irq_data() and then accessing the chip_data via irq_data_get_irq_chip_data(). | ||||

| In the Linux kernel, the following vulnerability has been resolved: soc: mediatek: svs: Fix memory leak in svs_enable_debug_write() In svs_enable_debug_write(), the buf allocated by memdup_user_nul() is leaked if kstrtoint() fails. Fix this by using __free(kfree) to automatically free buf, eliminating the need for explicit kfree() calls and preventing leaks. [Angelo: Added missing cleanup.h inclusion] | ||||
| CVE-2026-45921 | 1 Linux | 1 Linux Kernel | 2026-05-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mtd: parsers: Fix memory leak in mtd_parser_tplink_safeloader_parse() The function mtd_parser_tplink_safeloader_parse() allocates buf via mtd_parser_tplink_safeloader_read_table(). If the allocation for parts[idx].name fails inside the loop, the code jumps to the err_free label without freeing buf, leading to a memory leak. Fix this by freeing the temporary buffer buf in the err_free label. Compile tested only. Issue found using a prototype static analysis tool and code review. | ||||
| CVE-2026-45928 | 1 Linux | 1 Linux Kernel | 2026-05-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix memory leak on codec_info allocation failure In wave5_vpu_open_enc() and wave5_vpu_open_dec(), a vpu instance is allocated via kzalloc(). If the subsequent allocation for inst->codec_info fails, the functions return -ENOMEM without freeing the previously allocated instance, causing a memory leak. Fix this by calling kfree() on the instance in this error path to ensure it is properly released. | ||||
| CVE-2026-45926 | 1 Linux | 1 Linux Kernel | 2026-05-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: rust: pwm: Fix potential memory leak on init error When initializing a PWM chip using pwmchip_alloc(), the allocated device owns an initial reference that must be released on all error paths. If __pinned_init() were to fail, the allocated pwm_chip would currently leak because the error path returns without calling pwmchip_put(). | ||||
| CVE-2026-45939 | 1 Linux | 1 Linux Kernel | 2026-05-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: gpib: Fix memory leak in ni_usb_init() In ni_usb_init(), if ni_usb_setup_init() fails, the function returns -EFAULT without freeing the allocated writes buffer, leading to a memory leak. Additionally, ni_usb_setup_init() returns 0 on failure, which causes ni_usb_init() to return -EFAULT, an inappropriate error code for this situation. Fix the leak by freeing writes in the error path. Modify ni_usb_setup_init() to return -EINVAL on failure and propagate this error code in ni_usb_init(). | ||||
