high Nessus Plugin ID 157344

Language:

Synopsis

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

Description

The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0291-1 advisory.

 - A vulnerability was found in Linux Kernel where refcount leak in llcp_sock_bind() causing use-after-free which might lead to privilege escalations. (CVE-2020-25670)

 - A vulnerability was found in Linux Kernel, where a refcount leak in llcp_sock_connect() causing use-after- free which might lead to privilege escalations. (CVE-2020-25671)

 - A memory leak vulnerability was found in Linux kernel in llcp_sock_connect (CVE-2020-25672)

 - A vulnerability was found in Linux kernel where non-blocking socket in llcp_sock_connect() leads to leak and eventually hanging-up the system. (CVE-2020-25673)

 - u'Specifically timed and handcrafted traffic can cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for a discrete set of traffic' in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables, Snapdragon Wired Infrastructure and Networking in APQ8053, IPQ4019, IPQ8064, MSM8909W, MSM8996AU, QCA9531, QCN5502, QCS405, SDX20, SM6150, SM7150 (CVE-2020-3702)

 - Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability. (CVE-2021-23134)

 - A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.
 (CVE-2021-4154)

 - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or escalate privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-42739)

 - A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system. (CVE-2022-0185)

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 kernel-livepatch-5_3_18-24_49-default package.
