Kernel crash via unchecked display adapter EDID
Published Jul 9, 2025 · Updated May 11, 2026
Memory corruption in Linux kernel 6.13 through 6.15.4 allows physically proximate attackers to crash systems via malformed display EDID. The AMD display helper trusts a null or oversized drm_edid_raw() result without validating it against the fixed-size raw_edid array. A physically connected faulty or malicious adapter is required; a null result causes a kernel Oops, while excess EDID bytes can corrupt kernel memory.
