high Nessus Plugin ID 206220

Language:

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-6973-3 advisory.

 It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-24860)

 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:

 - SuperH RISC architecture;

 - MMC subsystem;

 - Network drivers;

 - SCSI drivers;

 - GFS2 file system;

 - IPv4 networking;

 - IPv6 networking;

 - HD-audio driver; (CVE-2024-26830, CVE-2024-39484, CVE-2024-36901, CVE-2024-26929, CVE-2024-26921, CVE-2021-46926, CVE-2023-52629, CVE-2023-52760)

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.
