Description
CVE-2026-99006 is a high-severity vulnerability in the Linux kernel's drm/i915/gem subsystem. It involves improper handling of the exec array boundary in the eb_relocate_parse_slow() function, which can lead to freeing memory outside the intended array. This occurs due to a mismatch between the buffer count used for cleanup and the actual exec object count, potentially causing memory corruption. The issue has been resolved by ensuring relocation cleanup uses the original exec object count, excluding appended VMAs.
