A flaw was found in the Bluetooth subsystem of the Linux kernel. During the system suspend process, a timing issue can occur where the hci_update_event_filter_sync() function attempts to access memory that has already been released. This Use-After-Free (UAF) vulnerability could allow a local attacker to cause a system crash, leading to a denial of service, or potentially execute arbitrary code with elevated privileges.
