CVE-2026-99006: drm/i915/gem: Prevent overstepping exec array boundary

Q: What condition leads to the invalid cleanup?

The condition occurs when relocation copies have been allocated for the original exec entries and the command parser then appends up to two VMAs after increasing eb->buffer_count. Error cleanup subsequently uses the increased count while freeing relocation pointers from the exec array.

Frequently Asked Questions

What condition leads to the invalid cleanup?

The condition occurs when relocation copies have been allocated for the original exec entries and the command parser then appends up to two VMAs after increasing eb->buffer_count. Error cleanup subsequently uses the increased count while freeing relocation pointers from the exec array.

What does the fix change?

The fix makes relocation cleanup use the original exec object count rather than the count after VMAs have been appended. This prevents kvfree() from being called on entries beyond the original exec array.
