Kernel-memory disclosure and interruption via undersized array
Published May 2, 2025 · Updated May 11, 2026
Out-of-bounds access in the i915 driver in the Linux kernel allows local users to read kernel memory or interrupt the system. During Gen11 i915 initialization, gen11_sseu_info_init can report eight subslices while eu_mask->hsw reserves six, so gen11_compute_sseu_info indexes past max_subslices. Low-privileged local access and a non-JSL/EHL Gen11 Intel graphics configuration are required; the published report demonstrates a UBSAN fault but no reliable exploit path.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
