An update that solves 10 vulnerabilities, contains three features and has 31 security fixes can now be installed.

Description:

The SUSE Linux Enterprise 15 SP4 RT kernel was updated to receive various security bugfixes.

The following security bugs were fixed:

  • CVE-2023-6531: Fixed a use-after-free flaw due to a race problem in the unix garbage collector's deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on (bsc#1218447).
  • CVE-2023-6610: Fixed an out of bounds read in the SMB client when printing debug information (bsc#1217946).
  • CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race condition in bt_sock_recvmsg (bsc#1218559).
  • 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-2023-6606: Fixed an out of bounds read in the SMB client when receiving a malformed length from a server (bsc#1217947).
  • CVE-2023-6546: Fixed a race condition in the GSM 0710 tty multiplexor via the GSMIOC_SETCONF ioctl that could lead to local privilege escalation (bsc#1218335).
  • CVE-2023-6931: Fixed a heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component that could lead to local privilege escalation. (bsc#1218258).
  • CVE-2023-6932: Fixed a use-after-free vulnerability in the Linux kernel's ipv4: igmp component that could lead to local privilege escalation (bsc#1218253).
  • CVE-2023-6622: Fixed a null pointer dereference vulnerability in nft_dynset_init() that could allow a local attacker with CAP_NET_ADMIN user privilege to trigger a denial of service (bsc#1217938).
  • CVE-2023-6121: Fixed an information leak via dmesg when receiving a crafted packet in the NVMe-oF/TCP subsystem (bsc#1217250).

The following non-security bugs were fixed:

  • Reviewed and added more information to README.SUSE (jsc#PED-5021).
  • Build in the correct KOTD repository with multibuild (JSC-SLE#5501, boo#1211226, bsc#1218184) With multibuild setting repository flags is no longer supported for individual spec files - see https://github.com/openSUSE/open-build-service/issues/3574 Add ExclusiveArch conditional that depends on a macro set up by bs-upload-kernel instead. With that each package should build only in one repository - either standard or QA. Note: bs-upload-kernel does not interpret rpm conditionals, and only uses the first ExclusiveArch line to determine the architectures to enable.
  • KVM: s390/mm: Properly reset no-dat (bsc#1218056).
  • KVM: s390: vsie: fix wrong VIR 37 when MSO is used (bsc#1217933).
