CVE-2024-26927 Information

Description

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.
