CVE-2024-42137

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a use-after-free error in the Linux kernel's Bluetooth component, specifically within the qca serdev shutdown() function. This error can cause a denial of service. The problem arises when the enable-gpios property is not configured within DT/ACPI for QCA6390, leading to a failure in enabling Bluetooth after a warm reboot. The fix involves sending the VSC to the reset controller within qca serdev shutdown() once Bluetooth was ever enabled, ensuring the serdev is still opened before it is flushed or wrote.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
