HIGH

Linux Kernel 5.19-6.1.82, 6.2.0-6.6.22, 6.7.0-6.7.10, 6.8.0-6.8.1 - Buffer Overflow in SOF Firmware Data Handling

Title source: llm
STIX 2.1

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.
