CVE-2026-45976 drm/amdgpu: Fix memory leak in amdgpu_ras_init()

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix memory leak in amdgpurasinit When amdgpunbiorasswinit fails in amdgpurasinit, the function returns directly without freeing the allocated con structure, leading to a memory leak. Fix this by jumping to the...

CVE-2026-45959

The CVE-2026-45959 issue affects the Linux kernel crypto: CCP driver. A local pointer annotated with __cleanup(kfree) could cause kfree to receive the local stack address instead of the allocated memory, leading to a crash. The underlying cause is incorrect cleanup usage; the repository indicates...

CVE-2026-45944

CVE-2026-45944 affects the Linux kernel IOMMU VT-d. During context-entry teardown, the implementation zeros a 128‑bit entry in two 64‑bit writes, risking a torn entry where the Present bit remains set while other fields are zeroed, potentially causing unpredictable behavior or spurious faults. Th...

CVE-2026-45931 accel/amdxdna: Hold mm structure across iommu_sva_unbind_device()

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Hold mm structure across iommusvaunbinddevice Some tests trigger a crash in iommusvaunbinddevice due to accessing iommumm after the associated mm structure has been freed. Fix this by taking an explicit reference t...

In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix memory leak in GETDATADIRECTSYSFSPATH handler The UVERBSHANDLERMLX5IBMETHODGETDATADIRECTSYSFSPATH function allocates memory for the device path using kobjectgetpath. If the length of the device path exceeds the...

CVE-2026-45921

CVE-2026-45921 affects the Linux kernel’s mtd: parsers component, specifically the function mtd_parser_tplink_safeloader_parse(). The issue arises when buf allocated by mtd_parser_tplink_safeloader_read_table() is not freed if parts[idx].name allocation fails inside the loop, causing a memory lea...

CVE-2026-45862

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Flush cache for PASID table before using it When writing the address of a freshly allocated zero-initialized PASID table to a PASID directory entry, do that after the CPU cache flush for this PASID table, not before i...

CVE-2026-45853

The CVE-2026-45853 issue is in the Linux kernel drm/amdgpu component. The function amdgpu_discovery_get_nps_info() allocates memory for ranges with kvcalloc() (potentially vmalloc), but frees it with kfree(), which may corrupt vmalloc memory. The documented fix is to use kvfree() to safely handle...

CVE-2026-45853

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Use kvfree instead of kfree in amdgpugmcgetnpsmemranges amdgpudiscoverygetnpsinfo internally allocates memory for ranges using kvcalloc, which may use vmalloc for large allocation. Using kfree to release vmalloc memor...
