______________________________________________________________________________
An update that solves 33 vulnerabilities, contains one
feature and has 9 fixes is now available.
Description:
The SUSE Linux Enterprise 15 SP2 RT kernel was updated to receive various
security bugfixes.
The following security bugs were fixed:
- 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-2022-28388: 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-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c
vulnerability in the Linux kernel (bnc#1198031).
- 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-2022-1055: Fixed a use-after-free in tc_new_tfilter that could allow
a local attacker to gain privilege escalation (bnc#1197702).
- 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-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-2022-26966: 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 local privilege escalation due to a
use-after-free bug in unix_gc (bsc#1193731).
-
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 trigger crash the system or
corrupt system memory (bsc#1196830).
- CVE-2022-0617: Fixed a null pointer dereference in UDF file system
functionality. A local user could crash the system by triggering
udf_file_write_iter() via a malicious UDF image (bsc#1196079).
- CVE-2022-25375: The RNDIS USB gadget lacks validation of the size of the
RNDIS_MSG_SET command. Attackers can obtain sensitive information from
kernel memory (bsc#1196235).
- CVE-2022-25258: The USB Gadget subsystem lacked certain validation of
interface OS descriptor requests, which could have lead to memory
corruption (bsc#1196096).
- CVE-2021-44879: In gc_data_segment() in fs/f2fs/gc.c, special files were
not considered, which lead to a move_data_page NULL pointer dereference
(bsc#1195987).
- CVE-2022-24959: Fixed a memory leak in yam_siocdevprivate() in
drivers/net/hamradio/yam.c (bsc#1195897).
- CVE-2022-24958: drivers/usb/gadget/legacy/inode.c mishandled dev->buf
release (bsc#1195905).
- CVE-2022-0516: Fixed missing check in ioctl related to KVM in s390
allows kernel memory read/write (bsc#1195516).
- CVE-2022-24448: Fixed an issue in fs/nfs/dir.c. If an application sets
the O_DIRECTORY flag, and tries to open a regular file,
nfs_atomic_open() performs a regular lookup. If a regular file is found,
ENOTDIR should have occured, but the server instead returned
uninitialized data in the file descriptor (bsc#1195612).
- CVE-2022-0492: Fixed a privilege escalation related to cgroups v1
release_agent feature, which allowed bypassing namespace isolation
unexpectedly (bsc#1195543).
- CVE-2022-28748: Fixed various information leaks that could be caused by
malicious USB devices (bsc#1196018).
- CVE-2022-0644: Fixed a denial of service by a local user. A assertion
failure could be triggered in kernel_read_file_from_fd() (bsc#1196155)
- CVE-2022-0850: Fixed a kernel information leak vulnerability in
iov_iter.c (bsc#1196761).
- 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).
The following non-security bugs were fixed:
- cifs: use the correct max-length for dentry_path_raw() (bsc#1196196).
- gve: multiple bugfixes (jsc#SLE-23652).
- net/mlx5e: Fix page DMA map/unmap attributes (bsc#1196468).
- netfilter: conntrack: do not refresh sctp entries in closed state
(bsc#1197389).
- powerpc/mm/numa: skip NUMA_NO_NODE onlining in parse_numa_properties()
(bsc#1179639).
- scsi: lpfc: Fix pt2pt NVMe PRLI reject LOGO loop (bsc#1189126).
- scsi: target: iscsi: Fix cmd abort fabric stop race (bsc#1195286).
