Ubuntu 22.04 LTS : Linux kernel (OEM) vulnerabilities (USN-5596-1)

medium Nessus Plugin ID 164670

Language:

Synopsis

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

Description

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5596-1 advisory.

 Asaf Modelevsky discovered that the Intel(R) 10GbE PCI Express (ixgbe) Ethernet driver for the Linux kernel performed insufficient control flow management. A local attacker could possibly use this to cause a denial of service. (CVE-2021-33061)

 It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655)

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.
