| CVE-2026-80701 | 1 Linux | 1 Linux Kernel | 2026-09-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: enforce cursor size limits for MOB cursors vmw_cursor_plane_atomic_check() bounds cursor width and height only on the legacy update path; the SVGA_CAP2_CURSOR_MOB path -- the default on modern hosts -- accepts any size. When the requested size exceeds SVGA_REG_CURSOR_MAX_DIMENSION or SVGA_REG_MOB_MAX_SIZE, vmw_cursor_mob_get() returns -EINVAL and leaves vps->cursor.mob NULL. Its return value is then discarded in vmw_cursor_plane_prepare_fb(), so the subsequent vmw_cursor_update_mob() calls vmw_bo_map_and_cache(NULL) and oopses inside vmw_bo_map_and_cache_size() on the tbo.base.size load. Reachable from any DRM master via DRM_IOCTL_MODE_CURSOR2 with a sufficiently large width or height (e.g. cursor_max_dim + 1). Reject oversized cursors in atomic_check for both MOB-backed cursor update types. The MOB byte-size limit only applies to the SVGA_CAP2_CURSOR_MOB path (vmw_cursor_mob_size() returns 0 for GB_ONLY); compute the required MOB size in 64-bit to avoid overflow when very large dimensions are requested. In prepare_fb only call vmw_cursor_mob_get()/_map() for VMW_CURSOR_UPDATE_MOB -- the GB_ONLY path uses bo->map.virtual directly and would otherwise be silently downgraded to NONE on hosts without SVGA_CAP2_CURSOR_MOB (where vmw_cursor_mob_get() always returns -EINVAL). Degrade the update to NONE if vmw_cursor_mob_get() or vmw_cursor_mob_map() fails so the update path does not run with a NULL backing MOB. | ||||

| Null pointer dereference for some Intel(R) PROSet/Wireless WiFi Software for Windows within Ring 2: Device Drivers may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts. | ||||

| CVE-2026-80621 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: PCI: dwc: Avoid dwc_pcie_rasdes_debugfs_deinit() NULL dereference when no RAS DES capability dwc_pcie_rasdes_debugfs_init() returns success when the controller has no RAS DES capability, leaving pci->debugfs->rasdes_info unset. The common debugfs teardown path still calls dwc_pcie_rasdes_debugfs_deinit(), which dereferences rasdes_info unconditionally. Return early when no RAS DES state was allocated. In that case no RAS DES mutex was initialized, so there is nothing to destroy. [mani: reworded subject] | ||||
| CVE-2026-80679 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: s390/dasd: Fix potential NULL pointer dereference dasd_release_space() checks the implementation of the is_ese() discipline function before calling it to determine if a given device is an ESE DASD. The current usage of the logical AND operator will lead to a NULL pointer dereference as the function is called even if the function pointer is NULL. Fix this by using the logical OR operator. | ||||
| CVE-2026-80636 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: revert ct extension genid infrastructure This infrastructure is not used anymore after moving ct timeout and helper to use datapath refcount to track object use. Revert commit c56716c69ce1 ("netfilter: extensions: introduce extension genid count") this patch disables all ct extensions (leading to NULL) for unconfirmed conntracks, when this is only targeted at ct helper and ct timeout. There is also codebase that dereferences the ct extension without checking for NULL which could lead to crash. | ||||
| CVE-2026-80658 | 1 Linux | 1 Linux Kernel | 2026-08-28 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: dw_dp: Fix null-ptr-deref in dw_dp_remove() Attempting to access driver data in the platform driver ->remove() callback may lead to a null pointer dereference since there is no guaranty that the component ->bind() callback invoking platform_set_drvdata() was executed. A common scenario is when Rockchip DRM driver didn't manage to run component_bind_all() because of an (unrelated) error causing early return from rockchip_drm_bind(). Drop the unnecessary call to platform_get_drvdata() and, instead, reference the target device structure via platform_device. | ||||
