Ubuntu 20.04 LTS : Linux kernel (OEM) vulnerability (USN-5346-1)

high Nessus Plugin ID 159192

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5346-1 advisory.

 It was discovered that the ICMPv6 implementation in the Linux kernel did not properly deallocate memory in certain situations. A remote attacker could possibly use this to cause a denial of service (memory exhaustion).

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
