CVE-2026-63880 drm/amdgpu: fix lock leak on ENOMEM in AMDGPU_GEM_OP_GET_MAPPING_INFO

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix lock leak on ENOMEM in AMDGPUGEMOPGETMAPPINGINFO The AMDGPUGEMOPGETMAPPINGINFO branch of amdgpugemopioctl holds three cleanup-tracked resources before calling kvcalloc: the drmgemobject reference from...

CVE-2026-63880

CVE-2026-63880 affects the Linux kernel AMDGPU driver (drm/amdgpu) in the AMDGPU_GEM_OP_GET_MAPPING_INFO path. A -ENOMEM failure in kvcalloc could skip cleanup and leak three locks (drm_gem_object reference, drm_exec lock on the GEM, and drm_exec lock on the per-process VM root PD), causing a loa...

SUSE CVE-2026-52987

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: avoid double drmexecfini in userq validate When newaddition is true, amdgpuuserqvmvalidate calls drmexecfini&exec before iterating over the collected HMM ranges and calling amdgputtmttgetuserpages. If...

CVE-2026-52987

A flaw was found in the Linux kernel. A double free vulnerability exists in the drm/amdgpu component within the userq validate function. This issue arises because the drmexecfini function is called twice on the same execution object, which is not designed to be idempotent. An attacker could...
