Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2809-1 advisory.

The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2020-36557: Fixed a race condition between the VT_DISALLOCATE ioctl and closing/opening of ttys could lead to a use-after-free (bnc#1201429).
- CVE-2020-36558: Fixed a race condition involving VT_RESIZEX which could lead to a NULL pointer dereference and general protection fault (bnc#1200910).
- CVE-2021-4157: Fixed an out of memory bounds write flaw in the NFS subsystem, related to the replication of files with NFS. A user could potentially crash the system or escalate privileges on the system (bsc#1194013).
- CVE-2021-26341: Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage (bsc#1201050).
- CVE-2021-33655: Fixed memory out of bounds write by ioctl cmd FBIOPUT_VSCREENINFO (bnc#1201635).
- CVE-2021-33656: Fixed memory out of bounds write related to ioctl cmd PIO_FONT (bnc#1201636).
- CVE-2022-1116: Fixed a integer overflow vulnerability in io_uring which allowed a local attacker to cause memory corruption and escalate privileges to root (bnc#1199647).
- CVE-2022-1462: Fixed an out-of-bounds read flaw in the TeleTYpe subsystem. This flaw allowed a local user to crash the system or read unauthorized random data from memory. (bnc#1198829)
- CVE-2022-1679: Fixed a use-after-free in the Atheros wireless driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages (bsc#1199487).
- CVE-2022-2318: Fixed a use-after-free vulnerabilities in the timer handler in net/rose/rose_timer.c that allow attackers to crash the system without any privileges (bsc#1201251).
- CVE-2022-20132: Fixed out of bounds read due to improper input validation in lg_probe and related functions of hid-lg.c (bsc#1200619).
- CVE-2022-20141: Fixed a possible use after free due to improper locking in ip_check_mc_rcu() (bsc#1200604).
- CVE-2022-20154: Fixed a use after free due to a race condition in lock_sock_nested of sock.c. This could lead to local escalation of privilege with System execution privileges needed (bsc#1200599).
- CVE-2022-21505: Fixed kexec lockdown bypass with ima policy (bsc#1201458).
- CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742: Fixed multiple potential data leaks with Block and Network devices when using untrusted backends (bsc#1200762).
- CVE-2022-29900, CVE-2022-29901: Fixed the RETBLEED attack, a new Spectre like Branch Target Buffer attack, that can leak arbitrary kernel information (bsc#1199657).
- CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692)
- CVE-2022-36946: Fixed incorrect packet truncation in nfqnl_mangle() that could lead to remote DoS (bnc#1201940).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
