CVE-2024-42237: firmware: cs_dsp: Validate payload length before processing block
First published: Wed Aug 07 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: firmware: cs_dsp: Validate payload length before processing block Move the payload length check in cs_dsp_load() and cs_dsp_coeff_load() to be done before the block is processed. The check that the length of a block payload does not exceed the number of remaining bytes in the firwmware file buffer was being done near the end of the loop iteration. However, some code before that check used the length field without validating it.
