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-2022:3704-1 advisory.

The SUSE Linux Enterprise 15 SP2 kernel was updated.

The following security bugs were fixed:

- CVE-2020-16119: Fixed a use-after-free vulnerability exploitable by a local attacker due to reuse of a DCCP socket. (bnc#1177471)
- CVE-2022-20008: Fixed a bug which allowed to read kernel heap memory due to uninitialized data. This could lead to local information disclosure if reading from an SD card that triggers errors, with no additional execution privileges needed. (bnc#1199564)
- CVE-2022-2503: Fixed a bug in dm-verity, device-mapper table reloads allowed users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allowed root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates (bnc#1202677).
- CVE-2022-2586: Fixed a use-after-free which can be triggered when a nft table is deleted (bnc#1202095).
- CVE-2022-32296: Fixed a bug which allowed TCP servers to identify clients by observing what source ports are used (bnc#1200288).
- CVE-2022-3239: Fixed an use-after-free in the video4linux driver that could lead a local user to able to crash the system or escalate their privileges (bnc#1203552).
- CVE-2022-3303: Fixed a race condition in the sound subsystem due to improper locking (bnc#1203769).
- CVE-2022-41218: Fixed an use-after-free caused by refcount races in drivers/media/dvb-core/dmxdev.c (bnc#1202960).
- CVE-2022-41222: Fixed a use-after-free via a stale TLB because an rmap lock is not held during a PUD move (bnc#1203622).
- CVE-2022-41674: Fixed a DoS issue where kernel can crash on the reception of specific WiFi Frames (bsc#1203770).
- CVE-2022-41848: Fixed a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling ioctl (bnc#1203987).
- CVE-2022-41849: Fixed a race condition and resultant use-after-free if a physically proximate attacker removes a USB device while calling open (bnc#1203992).
- CVE-2022-42719: Fixed remote code execution with wlan frames when parsing a multi-BSSID element (bsc#1204051).
- CVE-2022-42720: Fixed remote code execution due to refcounting bugs (bsc#1204059).
- CVE-2022-42721: Fixed remote code execution due list corruption in the wlan stack (bsc#1204060).

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.
