Two weaknesses have been reported in the Linux Kernel, which can be exploited by malicious, local users to disclose potential sensitive information.
The weaknesses are caused due to uninitialised variables within the "hci_sock_setsockopt()" function in net/bluetooth/hci_sock.c and the "l2cap_sock_setsockopt()" function in net/bluetooth/l2cap.c and can potentially be exploited to disclose uninitialised bytes of the kernel stack.
The weaknesses are reported in versions prior to 220.127.116.11.
Solution: Update to version 18.104.22.168.
Provided and/or discovered by: Reported by the vendor.
