CVE-2026-52987 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rtla package and not the rtla package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: avoid double drm_exec_fini() in userq validate
When new_addition is true, amdgpu_userq_vm_validate() calls drm_exec_fini(&exec) before iterating over the collected HMM ranges and calling amdgpu_ttm_tt_get_user_pages().
If amdgpu_ttm_tt_get_user_pages() fails in that path, the code jumps to unlock_all and calls drm_exec_fini(&exec) a second time on the same exec object. drm_exec_fini() is not idempotent: it frees exec->objects and may also drop exec->contended and finalize the ww acquire context.
Route that error path directly to the range cleanup once exec has already been finalized.
Issue found using a prototype static analysis tool and confirmed by code review.
(cherry picked from commit 2802952e4a07306da6ebe813ff1acacc5691851a)
