CVE-2024-42088

Kernel memory corruption via missing platform entry

Published Jul 29, 2024 · Updated Aug 5, 2026

Out-of-bounds access in Linux 6.8 on MediaTek MT8195 systems allows local users to corrupt kernel memory during sound-card probing. The ETDM1_OUT_BE link lacks a platform-array element because its codec entry was removed without an empty replacement, yet mtk_soundcard_common_probe() dereferences the first element. Exposure requires MT8195 hardware with the affected sound-card configuration; the invalid access occurs during platform-device probing.
