SUSE Linux Enterprise Real Time Extension 12-SP5
______________________________________________________________________________
An update that solves 10 vulnerabilities and has 15 fixes
is now available.
Description:
The SUSE Linux Enterprise 12 SP5 kernel rt was updated.
The following security bugs were fixed:
- CVE-2022-40768: Fixed information leak in the scsi driver which allowed
local users to obtain sensitive information from kernel memory.
(bnc#1203514)
- CVE-2022-3169: Fixed a denial of service flaw which occurs when
consecutive requests to NVME_IOCTL_RESET and the NVME_IOCTL_SUBSYS_RESET
are sent. (bnc#1203290)
- CVE-2022-3303: Fixed a race condition in the sound subsystem due to
improper locking (bnc#1203769).
- CVE-2022-41218: Fixed an use-after-free caused by refcount races in
drivers/media/dvb-core/dmxdev.c (bnc#1202960).
- CVE-2022-3239: Fixed an use-after-free in the video4linux driver that
could lead a local user to able to crash the system or escalate their
privileges (bnc#1203552).
- CVE-2022-41848: Fixed a race condition and resultant use-after-free if a
physically proximate attacker removes a PCMCIA device while calling
ioctl (bnc#1203987).
- CVE-2022-2503: Fixed a bug in dm-verity, device-mapper table reloads
allowed users with root privileges to switch out the target with an
equivalent dm-linear target and bypass verification till reboot. This
allowed root to bypass LoadPin and can be used to load untrusted and
unverified kernel modules and firmware, which implies arbitrary kernel
execution and persistence for peripherals that do not verify firmware
updates (bnc#1202677).
- CVE-2022-20008: Fixed a bug which allowed to read kernel heap memory due
to uninitialized data. This could lead to local information disclosure
if reading from an SD card that triggers errors, with no additional
execution privileges needed. (bnc#1199564)
- CVE-2022-40307: Fixed a race condition that could had been exploited to
trigger a use-after-free in the efi firmware capsule-loader.c.
(bnc#1203322)
- CVE-2022-3424: Fixed a use-after-free in gru_set_context_option which
was leading to kernel panic. (bsc#1204166)
The following non-security bugs were fixed:
- ACPI: processor idle: Practically limit "Dummy wait" workaround to old
Intel systems (bnc#1203802).

(bnc#1203802).
