What is CVE-2024-58238?

A vulnerability in the Linux kernel's Bluetooth module related to btnxpuart functionality has been addressed. The issue was identified during stress testing where a transmission timeout occurred that hindered Bluetooth communications. This was due to a race condition involving the power save mechanism, specifically when the UART breaking feature was turned on simultaneously with the transmission work. The resolution introduced a mutex around the power state transitions and UART break commands, ensuring proper synchronization. Testing confirmed that the TX timeout error did not recur after implementing this fix across extensive iterations.
