CVE-2024-50144

The CVE-2024-50144 issue affects the Linux kernel DRM/XE path. Root cause: an unbalanced rpm put() can occur if fence_fini() is invoked twice on error while handling GuC CT for a tlb request, because the code path signals the fence and then returns an error, causing the caller to run fini() again...

SUSE CVE-2024-49865

In the Linux kernel, the following vulnerability has been resolved: drm/xe/vm: move xaalloc to prevent UAF Evil user can guess the next id of the vm before the ioctl completes and then call vm destroy ioctl to trigger UAF since create ioctl is still referencing the same vm. Move the xaalloc all t...
