CVE-2024-41039 is an out-of-bounds read condition in the Linux kernel firmware: cs_dsp component while parsing WMFW firmware headers. The original firmware-buffer length validation checked the combined size of wmfw_header, wmfw_adsp1_sizes, and wmfw_footer. However, ADSP2 and Halo Core firmware use wmfw_adsp2_sizes, which is four bytes larger than the ADSP1-specific structure. Consequently, the check could accept an insufficient buffer before the larger ADSP2/Halo Core header structure was accessed. The fix validates wmfw_header, the applicable firmware-size structure, and wmfw_footer separately before use.
