The SUSE Linux Enterprise 12 SP5 kernel was updated.
The following security bugs were fixed:
- CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the
netfilter subsystem. This vulnerability gives an attacker a powerful
primitive that can be used to both read from and write to relative stack
data, which can lead to arbitrary code execution. (bsc#1197227)
- CVE-2022-28389: Fixed a double free in drivers/net/can/usb/mcba_usb.c
vulnerability in the Linux kernel. (bnc#1198033)
- CVE-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c
vulnerability in the Linux kernel. (bnc#1198031)
- CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c
vulnerability in the Linux kernel. (bnc#1198032)
- CVE-2022-0812: Fixed an incorrect header size calculations which could
lead to a memory leak. (bsc#1196639)
- CVE-2022-1048: Fixed a race Condition in snd_pcm_hw_free leading to
use-after-free due to the AB/BA lock with buffer_mutex and mmap_lock.
(bsc#1197331)
- CVE-2022-0850: Fixed a kernel information leak vulnerability in
iov_iter.c. (bsc#1196761)
- CVE-2022-26966: Fixed an issue in drivers/net/usb/sr9700.c, which
allowed attackers to obtain sensitive information from the memory via
crafted frame lengths from a USB device. (bsc#1196836)
- CVE-2021-45868: Fixed a wrong validation check in fs/quota/quota_tree.c
which could lead to an use-after-free if there is a corrupted quota
file. (bnc#1197366)
- CVE-2021-39713: Fixed a race condition in the network scheduling
subsystem which could lead to a use-after-free. (bnc#1196973)
-
CVE-2022-23036,CVE-2022-23037,CVE-2022-23038,CVE-2022-23039,CVE-2022-23040,
CVE-2022-23041,CVE-2022-23042: Fixed multiple issues which could have
lead to read/write access to memory pages or denial of service. These
issues are related to the Xen PV device frontend drivers. (bsc#1196488)
- CVE-2022-26490: Fixed a buffer overflow in the st21nfca driver. An
attacker with adjacent NFC access could crash the system or corrupt the
system memory. (bsc#1196830)
- CVE-2022-0001,CVE-2022-0002,CVE-2022-23960: Fixed a new kind of
speculation issues, exploitable via JITed eBPF for instance.
(bsc#1191580)
- CVE-2022-27666: Fixed a buffer overflow vulnerability in IPsec ESP
transformation code. This flaw allowed a local attacker with a normal
user privilege to overwrite kernel heap objects and may cause a local
privilege escalation. (bnc#1197462)
