- Summary
- drm/xe: free madvise VMA array on L2 flush failure
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/xe: free madvise VMA array on L2 flush failure
xevmmadviseioctl() allocates madviserange.vmas in getvmas(). After getvmas() succeeds with at least one VMA, error paths must go through free_vmas so the array is released before the madvise details are destroyed.
The L2 flush validation path added for PAT madvise rejects some SVM/userptr ranges after getvmas() has succeeded, but jumps directly to madvfini. This skips kfree(madvise_range.vmas), leaking the VMA array on each failed ioctl.
Jump to freevmas instead, matching the other validation failure paths after getvmas() has succeeded.
(cherry picked from commit c3a1c3579b1250060da73507a4acef712974c78a)
