CVE-2024-46867 drm/xe/client: fix deadlock in show_meminfo()

In the Linux kernel, the following vulnerability has been resolved: drm/xe/client: fix deadlock in showmeminfo There is a real deadlock as well as sleeping in atomic bug in here, if the bo put happens to be the last ref, since bo destruction wants to grab the same spinlock and sleeping locks. Fix...

CVE-2024-46867

In CVE-2024-46867, the Linux kernel component drm/xe/client exhibited a deadlock and an atomic sleep issue in show_meminfo when the bo (buffer object) being destroyed had the last reference. The root cause was the destruction path attempting to grab the same spinlock, risking a sleep in atomic co...

CVE-2024-46866

The CVE-2024-46866 issue in the Linux kernel affects the drm/xe client, specifically the bo_meminfo path. Root cause: bo_meminfo() inspects bo state (tt and ttm resource) without consistently holding the bo lock, allowing state changes that can cause NPD or UAF. Mitigation implemented by grabbing...
