Linux · Linux Kernel · CVE-2026-52987
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A double free flaw exists in the `drm/amdgpu` component within the `userq validate` function. The issue occurs when `amdgpu userq vm validate()` calls the `drm exec fini()` function on an execution object, and subsequently calls it a second time if `amdgpu ttm tt get user pages()` fails. Because `drm exec fini()` is not idempotent, it may incorrectly free objects and finalize the ww acquire context, potentially leading to a denial of service or unpredictable system behavior.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
