Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> accel/ivpu: Fix race condition when unbinding BOs<br /> <br /> Fix &amp;#39;Memory manager not clean during takedown&amp;#39; warning that occurs<br /> when ivpu_gem_bo_free() removes the BO from the BOs list before it<br /> gets unmapped. Then file_priv_unbind() triggers a warning in<br /> drm_mm_takedown() during context teardown.<br /> <br /> Protect the unmapping sequence with bo_list_lock to ensure the BO is<br /> always fully unmapped when removed from the list. This ensures the BO<br /> is either fully unmapped at context teardown time or present on the<br /> list and unmapped by file_priv_unbind().
