Affected Products:
SUSE Linux Enterprise Server 12-SP2-BCL
______________________________________________________________________________
An update that solves 9 vulnerabilities and has three fixes
is now available.
Description:
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/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).
- 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 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).
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 report_list in hid_validate_values() (git-fixes,
bsc#1206784).
- sctp: fail if no bound addresses can be used for a given scope
(bsc#1206677).
