There are use-after-free vulnerabilities in the Linux kernel’s
net/bluetooth/l2cap_core.c’s l2cap_connect and l2cap_le_connect_req
functions which may allow code execution and leaking kernel memory
(respectively) remotely via Bluetooth. A remote attacker could execute code
leaking kernel memory via Bluetooth if within proximity of the victim. We
recommend upgrading past commit https://www.google.com/url
https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4
