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-2026-45921

In the Linux kernel, the memory leak in mtd_parser_tplink_safeloader_parse() was resolved. The function allocates a temporary buffer buf via mtd_parser_tplink_safeloader_read_table(), and if parts[idx].name allocation fails inside the loop, control jumps to err_free without freeing buf. The fix a...

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

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...

CVE-2026-45853

In the Linux kernel vulnerability CVE-2026-45853, the AMDGPU driver component amdgpu_gmc_get_nps_memranges() allocated ranges with kvcalloc() (which may use vmalloc()) and previously released memory with kfree(), risking memory corruption when vmalloc memory is involved. The remediation is to use...
