CVE-2025-68749 is a medium-severity vulnerability rated 4.7/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Fix race condition when unbinding BOs Fix 'Memory manager not clean during takedown' warning that occurs when ivpu_gem_bo_free() removes the BO from the BOs list before it gets unmapped. Then file_priv_unbind() triggers a warning in drm_mm_takedown() during context teardown. Protect the unmapping sequence with bo_list_lock to ensure the BO is always fully unmapped when removed from the list. EPSS estimates a 0.09% chance of exploitation in the next 30 days.

Description

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Fix race condition when unbinding BOs Fix 'Memory manager not clean during takedown' warning that occurs when ivpu_gem_bo_free() removes the BO from the BOs list before it gets unmapped. Then file_priv_unbind() triggers a warning in drm_mm_takedown() during context teardown. Protect the unmapping sequence with bo_list_lock to ensure the BO is always fully unmapped when removed from the list. This ensures the BO is either fully unmapped at context teardown time or present on the list and unmapped by file_priv_unbind().
