Affected Products:
* SUSE Linux Enterprise Micro 5.1
* SUSE Linux Enterprise Micro 5.2
* SUSE Linux Enterprise Micro for Rancher 5.2
An update that solves 17 vulnerabilities, contains two features and has four
security 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:

privilege, causing a denial of service (bsc#1203517).
* CVE-2023-2007: Fixed a flaw in the DPT I2O Controller driver that could
allow an attacker to escalate privileges and execute arbitrary code in the
context of the kernel (bsc#1210448).

pointer leading to a possible kernel crash and denial of service
(bsc#1213666).

information leak issue (bsc#1213601).
* CVE-2023-4128: Fixed a use-after-free flaw in net/sched/cls_fw.c that
allowed a local attacker to perform a local privilege escalation due to
incorrect handling of the existing filter, leading to a kernel information
leak issue (bsc#1214149).

alloawed a local privileged attacker to overflow the kernel stack
(bsc#1214120).

allowed a local attacker to crash the system due to a missing sanity check
(bsc#1214348).
* CVE-2023-4387: Fixed use-after-free flaw in vmxnet3_rq_alloc_rx_buf that
could allow a local attacker to crash the system due to a double-free
(bsc#1214350).
* CVE-2023-4459: Fixed a NULL pointer dereference flaw in vmxnet3_rq_cleanup
that may have allowed a local attacker with normal user privilege to cause a
denial of service (bsc#1214451).
* CVE-2023-20588: Fixed a division-by-zero error on some AMD processors that
can potentially return speculative data resulting in loss of confidentiality
(bsc#1213927).
