What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

No structured fix or remediation guidance is available here. Check the full source description and vendor’s latest advisory for a patch or workaround; do not assume another version is safe.

Original source description

Read the full publisher description

In the Linux kernel, the following vulnerability has been resolved:

drm/i915/gem: Prevent overstepping exec array boundary

It is possible for eb_relocate_parse_slow() to call kvfree() on entries outside the original exec array during following scenario inside eb_relocate_parse_slow():

  1. eb_copy_relocations() allocates as many as eb->buffer_count copies for exec entries;
  2. eb_parse() appends up to two VMAs, right after incrementing eb->buffer_count;
  3. cleanup under "out" label uses this incremented buffer_count to release relocation pointers from exec array via kvfree(), not from VMA array.

To amend this problem, ensure that relocation cleanup uses the original exec object count, excluding the VMAs appended by the command parser.

(cherry picked from commit 2a0158925fb943c7ba8f3216e2734952128defc9)
