CVE-2024-50030

CVE-2024-50030 refers to a Linux kernel vulnerability in drm/xe/ct where a use-after-free (UAF) could occur due to fence/timeout interactions. The fix serializes with the completion side by grabbing ct->lock after the wait to ensure correct ordering of dependent loads/stores and to prevent UAF...

CVE-2024-50030 drm/xe/ct: prevent UAF in send_recv()

In the Linux kernel, the following vulnerability has been resolved: drm/xe/ct: prevent UAF in sendrecv Ensure we serialize with completion side to prevent UAF with fence going out of scope on the stack, since we have no clue if it will fire after the timeout before we can erase from the xa. Also ...

CVE-2024-49876

CVE-2024-49876 affects the Linux kernel DRM-Xe path. The issue is a use-after-free (UAF) around queue destruction where final destruction steps could run on a workqueue that outlives the driver instance, risking references to freed objects. The fix adds a fini step to ensure user queues are torn ...

CVE-2024-49865

CVE-2024-49865 affects the Linux kernel’s DRM XE VM code. The root cause is a use-after-free risk caused by the timing of allocating VM IDs with xa_alloc, which allowed an Evil user to guess the next VM id before vm destroy/ioctl completes, potentially exposing references to the same VM that is s...
