Description

In the Linux kernel, the following vulnerability has been resolved: firmware: cs_dsp: Fix overflow checking of wmfw header Fix the checking that firmware file buffer is large enough for the wmfw header, to prevent overrunning the buffer. The original code tested that the firmware data buffer contained enough bytes for the sums of the size of the structs wmfw_header + wmfw_adsp1_sizes + wmfw_footer But wmfw_adsp1_sizes is only used on ADSP1 firmware. For ADSP2 and Halo Core the equivalent struct is wmfw_adsp2_sizes, which is 4 bytes longer. So the length check didn't guarantee that there are enough bytes in the firmware buffer for a header with wmfw_adsp2_sizes. This patch splits the length check into three separate parts. Each of the wmfw_header, wmfw_adsp?_sizes and wmfw_footer are checked separately before they are used.

Techniques & Countermeasures

  • CWE-120•Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

    The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.
