CVE-2026-45979

The CVE affects the Linux kernel DRM/amdgpu path, specifically the amdgpu_cs_parser_bos cleanup. In low memory conditions, kmalloc can fail, and the fix ensures a clean exit by unlocking the mutex. It also notes that amdgpu_bo_list_put is not needed, as that work is handled in amdgpu_cs_parser_fi...

CVE-2026-45979 drm/amdgpu: clean up the amdgpu_cs_parser_bos

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: clean up the amdgpucsparserbos In low memory conditions, kmalloc can fail. In such conditions unlock the mutex for a clean exit. We do not need to amdgpubolistput as it's been handled in the amdgpucsparserfini...

CVE-2026-45976

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-2026-45976

CVE-2026-45976 affects the Linux kernel DRM/AMDGPU ras init path. The root cause is a memory leak: when amdgpu_nbio_ras_sw_init() fails inside amdgpu_ras_init(), the function returns without freeing the allocated con structure. The fix jumps to the release_con label to properly release the alloca...

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-2026-45947

In the Linux kernel DRM/AMDGPU code, a memory leak was fixed in amdgpu_acpi_enumerate_xcc(). If amdgpu_acpi_dev_init() returns -ENOMEM, xcc_info could be leaked because it wasn’t freed in the error path. The fix ensures that xcc_info is properly freed on error paths, preventing the leak. This ana...

CVE-2026-45878

The CVE-2026-45878 issue affects the Linux kernel’s AMD GPU driver (drm/amdkfd) where debug address watch (watch_id) handling could overflow memory due to mixing unsigned watch_id with signed checks. The root cause is insufficient bounds validation for watch_id, which could be large enough to acc...

CVE-2026-45878 drm/amdkfd: Fix watch_id bounds checking in debug address watch v2

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix watchid bounds checking in debug address watch v2 The address watch clear code receives watchid as an unsigned value u32, but some helper functions were using a signed int and checked bits by shifting with watchid...

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...
