Description OSIDB Bzimport 2026-04-22 15:03:13 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/xe/pf: Fix use-after-free in migration restore

When an error is returned from xe_sriov_pf_migration_restore_produce(),
the data pointer is not set to NULL, which can trigger use-after-free
in subsequent .write() calls.
Set the pointer to NULL upon error to fix the problem.

(cherry picked from commit 4f53d8c6d23527d734fe3531d08e15cb170a0819)
