• CVE-2022-3564: Fixed use-after-free in l2cap_core.c of the Bluetooth component (bsc#1206073).
• CVE-2022-3643: Fixed reset/abort/crash via netback from VM guest (bsc#1206113).
• CVE-2022-42895: Fixed an information leak in the net/bluetooth/l2cap_core.c's l2cap_parse_conf_req() which can be used to leak kernel pointers remotely (bsc#1205705).
• CVE-2022-42896: Fixed a use-after-free vulnerability in the net/bluetooth/l2cap_core.c's l2cap_connect() and l2cap_le_connect_req() which may have allowed code execution and leaking kernel memory (respectively) remotely via Bluetooth (bsc#1205709).
• CVE-2022-4662: Fixed incorrect access control in the USB core subsystem that could lead a local user to crash the system (bsc#1206664).
