Affected Products:
* SUSE Linux Enterprise Micro 5.1
* SUSE Linux Enterprise Micro 5.2

An update that solves seven vulnerabilities, contains one feature and has six
security fixes can now be installed.
## Description:
The SUSE Linux Enterprise 15 SP3 RT kernel was updated to receive various
security bugfixes.
The following security bugs were fixed:
* CVE-2020-26555: Fixed an issue during BR/EDR PIN code pairing in the
Bluetooth subsystem that would allow replay attacks (bsc#1179610
bsc#1215237).
* CVE-2023-6121: Fixed an information leak via dmesg when receiving a crafted
packet in the NVMe-oF/TCP subsystem (bsc#1217250).
* CVE-2023-6606: Fixed an out of bounds read in the SMB client when receiving
a malformed length from a server (bsc#1217947).
* CVE-2023-6610: Fixed an out of bounds read in the SMB client when printing
debug information (bsc#1217946).
* CVE-2023-6931: Fixed an out of bounds write in the Performance Events
subsystem when adding a new event (bsc#1218258).
* CVE-2023-6932: Fixed a use-after-free issue when receiving an IGMP query
packet due to reference count mismanagement (bsc#1218253).
* CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race
condition in bt_sock_recvmsg (bsc#1218559).
The following non-security bugs were fixed:
* Reviewed and added more information to README.SUSE (jsc#PED-5021).
* Enabled multibuild for kernel packages (JSC-SLE#5501, boo#1211226,
bsc#1218184).
* clocksource: Avoid accidental unstable marking of clocksources
(bsc#1218105).
* clocksource: Suspend the watchdog temporarily when high read latency
detected (bsc#1218105).
* efi/mokvar: Reserve the table only if it is in boot services data
(bsc#1215375).
