Ubuntu 18.04 LTS : Linux kernel (HWE) vulnerabilities (USN-7234-2)

high Nessus Plugin ID 214831

Synopsis

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

Description

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7234-2 advisory.

 Ye Zhang and Nicolas Wu discovered that the io_uring subsystem in the Linux kernel did not properly handle locking for rings with IOPOLL, leading to a double-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-21400)

 Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems:

 - TTY drivers;

 - Netfilter;

 - Network traffic control;

 - VMware vSockets driver; (CVE-2024-53141, CVE-2024-53103, CVE-2024-40967, CVE-2024-53164)

Tenable has extracted the preceding description block directly from the Ubuntu 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 kernel package.
