The SUSE Linux Enterprise 15 SP2 kernel was updated.
The following security bugs were fixed:
- 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-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)
- CVE-2022-0850: Fixed a kernel information leak vulnerability in
iov_iter.c. (bsc#1196761)
- CVE-2022-1055: Fixed a use-after-free in tc_new_tfilter that could allow
a local attacker to gain privilege escalation. (bnc#1197702)
- 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-2022-28390: 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-2022-28389: Fixed a double free in drivers/net/can/usb/mcba_usb.c
vulnerability in the Linux kernel. (bnc#1198033)
- 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-2022-0854: Fixed a memory leak flaw was found in the Linux kernels
DMA subsystem. This flaw allowed a local user to read random memory from
the kernel space. (bnc#1196823)
- 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-2021-39698: Fixed a possible memory corruption due to a use after
free in aio_poll_complete_work. This could lead to local escalation of
privilege with no additional execution privileges needed. (bsc#1196956)
- CVE-2021-0920: Fixed a race condition during UNIX socket garbage
collection that could lead to local privilege escalation. (bsc#119373)
-
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)
