What to do
AI-suggested
A fix is available that bounds the string print to the actual response length, preventing out-of-bounds reads. Users should update to a Linux kernel version that includes this fix. No additional action is required as the fix does not disrupt device functionality and mitigates the issue fully.
Description
A vulnerability in the Linux kernel Bluetooth bpa10x driver allowed an out-of-bounds read of the revision string in the bpa10x_setup() function. This occurred because the code passed a response string to kernel functions without verifying its length, potentially reading adjacent memory beyond the valid data. The issue was fixed by bounding the string print to the actual response length, preventing out-of-bounds reads while maintaining device functionality.
