CWE ID 667
Summary
CVE-2024-46866 is a vulnerability affecting the Linux kernel. In the drm/xe/client driver, there was a failure to properly lock a buffer object (bo) before calling the function bo_meminfo(), leading to potential issues such as use-after-free (UAF) and null pointer dereference (NPD). This vulnerability was resolved by adding missing locking in show_meminfo() and holding the bo lock before inspecting its state. Additionally, the commit introduced xe_bo_assert_held() to ensure the bo is held before calling bo_meminfo().
