Summary

Security update for the Linux Kernel

Details

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

CVE-2018-9517: Fixed possible memory corruption due to a use after free in pppol2tp_connect (bsc#1108488).
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/l2capcore.c's l2capparseconfreq() which can be used to leak kernel pointers remotely (bsc#1205705).
CVE-2022-42896: Fixed a use-after-free vulnerability in the net/bluetooth/l2capcore.c's l2capconnect() and l2capleconnect_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).
CVE-2022-47929: Fixed NULL pointer dereference bug in the traffic control subsystem (bsc#1207237).
CVE-2023-23454: Fixed a type-confusion in the CBQ network scheduler (bsc#1207036).
CVE-2023-23455: Fixed a denial of service inside atmtcenqueue in net/sched/schatm.c because of type confusion (non-negative numbers can sometimes indicate a TCACT_SHOT condition rather than valid classification results) (bsc#1207125).

The following non-security bugs were fixed:

HID: betop: check shape of output reports (git-fixes, bsc#1207186).
HID: betop: fix slab-out-of-bounds Write in betop_probe (git-fixes).
HID: check empty reportlist in hidvalidate_values() (git-fixes, bsc#1206784).
sctp: fail if no bound addresses can be used for a given scope (bsc#1206677).
