Vulnerability from github – Published: 2025-12-24 12:30 – Updated: 2026-07-30 06:32

Details

In the Linux kernel, the following vulnerability has been resolved:

accel/ivpu: Fix page fault in ivpu_bo_unbind_all_bos_from_context()

Don't add BO to the vdev->bo_list in ivpu_gem_create_object(). When failure happens inside drm_gem_shmem_create(), the BO is not fully created and ivpu_gem_bo_free() callback will not be called causing a deleted BO to be left on the list.

Severity

7.8 (High)
