Published: August 9, 2024Last modified: August 9, 2024
Description
In the Linux kernel, the following vulnerability has been resolved: firmware: cs_dsp: Return error if block header overflows file Return an error from cs_dsp_power_up() if a block header is longer than the amount of data left in the file. The previous code in cs_dsp_load() and cs_dsp_load_coeff() would loop while there was enough data left in the file for a valid region. This protected against overrunning the end of the file data, but it didn't abort the file processing with an error.
