Description OSIDB Bzimport 2026-04-03 16:02:47 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Fix memory leak in xe_vm_madvise_ioctl

When check_bo_args_are_sane() validation fails, jump to the new
free_vmas cleanup label to properly free the allocated resources.
This ensures proper cleanup in this error path.
