Synopsis

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

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0198-1 advisory.

The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2022-0185: Incorrect param length parsing in legacy_parse_param which could have led to a local privilege escalation (bsc#1194517).
- CVE-2022-0322: Fixed a denial of service in SCTP sctp_addto_chunk (bsc#1194985).
- CVE-2021-4197: Fixed a cgroup issue where lower privileged processes could write to fds of lower privileged ones that could lead to privilege escalation (bsc#1194302).
- CVE-2021-46283: nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own namespace (bnc#1194518).
- CVE-2021-4135: Fixed an information leak in the nsim_bpf_map_alloc function (bsc#1193927).
- CVE-2021-4202: Fixed a race condition during NFC device remove which could lead to a use-after-free memory corruption (bsc#1194529)
- CVE-2021-4083: A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allowed a local user to crash the system or escalate their privileges on the system. This flaw affects Linux kernel versions prior to 5.16-rc4 (bnc#1193727).
- CVE-2021-4149: Fixed a locking condition in btrfs which could lead to system deadlocks (bsc#1194001).
- CVE-2021-45485: In the IPv6 implementation in net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses (bnc#1194094).
- CVE-2021-45486: In the IPv4 implementation in net/ipv4/route.c has an information leak because the hash table is very small (bnc#1194087).

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.
