CVE-2024-42237 is a medium severity vulnerability in the Linux kernel's firmware component cs_dsp. The issue involves improper validation of the payload length before processing a block in the cs_dsp_load() and cs_dsp_coeff_load() functions. The payload length check was performed too late in the processing loop, allowing some code to use an unvalidated length field, which could lead to a denial of service (DoS) condition.
