  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-21990
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: NULL-check BO's backing store when determining GFX12 PTE flags PRT BOs may not have any backing store, so bo->tbo.resource will be NULL. Check for that before dereferencing. (cherry picked from commit 3e3fcd29b505cebed659311337ea03b7698767fc)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amdgpu: Se ha comprobado el almacenamiento de respaldo del BO al determinar los indicadores PTE de GFX12. Los BO de PRT podrían no tener almacenamiento de respaldo, por lo que bo->tbo.resource será nulo. Compruébelo antes de desreferenciar.
