CVE-2022-48889

Module build failure via overlong platform alias

Published Aug 21, 2024 · Updated May 11, 2026

Incorrect buffer-size handling in Linux kernel 5.17 through 6.1.6 causes a compiler failure in the sof-nau8825 module. An ASoC Intel platform_device_id entry exceeds its 20-byte buffer including the terminating NUL, causing MODULE_ALIAS to encode trailing bytes as invalid characters. Reachability is confined to compiling the affected Intel SOF NAU8825 machine driver, and the documented consequence is build interruption rather than runtime compromise.
