CVE-2024-41056 is an out-of-bounds read vulnerability in the Linux kernel firmware cs_dsp component when parsing Version 1 WMFW firmware files. Algorithm and coefficient names are stored in fixed-size arrays and are expected to be NUL-terminated. The affected code used strlen(), which can continue reading beyond the array boundary if a malformed name field lacks a NUL terminator. The fix replaces unbounded strlen() calls with bounded strnlen() calls.
