- Summary
- drm/xe/pt: Fix NULL pointer dereference in xe_pt_zap_ptes_entry()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/pt: Fix NULL pointer dereference in xeptzapptesentry()
The page-table walk framework may pass a NULL *child pointer for unpopulated entries. xeptzapptesentry() called container_of(*child) before checking for NULL, then dereferenced the result, causing a crash.
Move the containerof() call after a NULL guard, so the function returns early instead of proceeding with an invalid pointer. XEWARN_ON is kept to help root cause the issue, but we now bail instead of crashing the driver.
v2: Comment that triggering XEWARNON is unexpected behavior (Matt Brost)
(cherry picked from commit b9297d19d9df5d4b6c994648570c5dcd1cac68ff)
