| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/i915/sseu: fix max_subslices array-index-out-of-bounds access\n\nIt seems that commit bc3c5e0809ae (\"drm/i915/sseu: Don't try to store EU\nmask internally in UAPI format\") exposed a potential out-of-bounds\naccess, reported by UBSAN as following on a laptop with a gen 11 i915\ncard:\n\n UBSAN: array-index-out-of-bounds in drivers/gpu/drm/i915/gt/intel_sseu.c:65:27\n index 6 is out of range for type 'u16 [6]'\n CPU: 2 PID: 165 Comm: systemd-udevd Not tainted 6.2.0-9-generic #9-Ubuntu\n Hardware name: Dell Inc.
