CVE-2024-41039 is a high-severity vulnerability in the Linux kernel's firmware handling for cs_dsp devices. The flaw involves improper overflow checking of the wmfw firmware header, specifically failing to correctly verify the buffer size for certain firmware types (ADSP2 and Halo Core). This could lead to a buffer overrun when processing the firmware header. The issue was fixed by splitting the length check into separate validations for each header component to ensure the buffer is large enough before use.
