update for the Linux Kernel","details":"\nThe SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.\n\n\nThe following security bugs were fixed:\n\n- CVE-2018-9517: Fixed possible memory corruption due to a use after free in pppol2tp_connect (bsc#1108488).\n- CVE-2022-3564: Fixed use-after-free in l2cap_core.c of the Bluetooth component (bsc#1206073).\n- CVE-2022-3643: Fixed reset/abort/crash via netback from VM guest (bsc#1206113).\n- 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).\n- 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).\n- CVE-2022-4662: Fixed incorrect access control in the USB core subsystem that could lead a local user to crash the system (bsc#1206664).\n- CVE-2022-47929: Fixed NULL pointer dereference bug in the traffic control subsystem (bsc#1207237).\n- CVE-2023-23454: Fixed a type-confusion in the CBQ network scheduler (bsc#1207036).\n- CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207125).\n\nThe following non-security bugs were fixed:\n\n- HID: betop: check shape of output reports (git-fixes, bsc#1207186).\n- HID: betop: fix slab-out-of-bounds Write in betop_probe (git-fixes).\n- HID: check empty report_list in hid_validate_values() (git-fixes, bsc#1206784).\n- sctp: fail if no bound addresses can be used for a given scope (bsc#1206677).\n","affected":[{"package":{"name":"kernel-default","ecosystem":"SUSE:Linux Enterprise Server 12
