o SUSE Linux Enterprise Micro 5.1
Affected o SUSE Linux Enterprise Micro 5.2
Products: o SUSE Linux Enterprise Micro for Rancher 5.2
o SUSE Linux Enterprise Real Time 15 SP3
o SUSE Real Time Module 15-SP3
An update that solves 15 vulnerabilities and has five fixes can now be
installed.
Description:
The SUSE Linux Enterprise 15 SP3 RT kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
o CVE-2023-2124: Fixed an out of bound access in the XFS subsystem that could
have lead to denial-of-service or potentially privilege escalation (bsc#
1210498).
o CVE-2023-1872:Fixed a use after free vulnerability in the io_uring
subsystem, which could lead to local privilege escalation (bsc#1210414).
o CVE-2022-2196: Fixed a regression related to KVM that allowed for
speculative execution attacks (bsc#1206992).
o CVE-2023-1670: Fixed a use after free in the Xircom 16-bit PCMCIA Ethernet
driver. A local user could use this flaw to crash the system or potentially
escalate their privileges on the system (bsc#1209871).
o CVE-2023-2162: Fixed an use-after-free flaw in iscsi_sw_tcp_session_create
(bsc#1210647).
o CVE-2023-2176: A vulnerability was found in compare_netdev_and_ip in
drivers/infiniband/core/cma.c in RDMA. The improper cleanup results in
out-of-boundary read, where a local user can utilize this problem to crash
the system or escalation of privilege (bsc#1210629).
o CVE-2023-1998: Fixed a use after free during login when accessing the shost
ipaddress (bsc#1210506).
o CVE-2023-30772: Fixed a race condition and resultant use-after-free in
da9150_charger_remove (bsc#1210329).
o CVE-2023-2008: A flaw was found in the fault handler of the udmabuf device
driver. An attacker can leverage this vulnerability to escalate privileges
and execute arbitrary code (bsc#1210453).
o CVE-2023-1855: Fixed a use after free in xgene_hwmon_remove (bsc#1210202).
o CVE-2020-36691: Fixed a denial of service vulnerability via a nested
Netlink policy with a back reference (bsc#1209777).
o CVE-2023-1990: Fixed a use after free in ndlc_remove (bsc#1210337).
o CVE-2023-1989: Fixed a use after free in btsdio_remove (bsc#1210336).
o CVE-2023-1611: Fixed an use-after-free flaw in btrfs_search_slot (bsc#
1209687).
o CVE-2023-1838: Fixed an use-after-free flaw in virtio network subcomponent.
This flaw could allow a local attacker to crash the system and lead to a
kernel information leak problem. (bsc#1210203).
The following non-security bugs were fixed:
o Drivers: vmbus: Check for channel allocation before looking up relids
(git-fixes).
o cifs: fix negotiate context parsing (bsc#1210301).
o keys: Fix linking a duplicate key to a keyring's assoc_array (bsc#1207088).
o vmxnet3: use gro callback when UPT is enabled (bsc#1209739).
