Vulnerability from github – Published: 2024-04-28 12:30 – Updated: 2024-07-03 18:37

Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: Add some bounds checking to firmware data

Smatch complains about "head->full_size - head->header_size" can underflow. To some extent, we're always going to have to trust the firmware a bit. However, it's easy enough to add a check for negatives, and let's add a upper bounds check as well.

Severity ?

8.4 (High)
