Ubuntu 16.04 ESM : Linux kernel vulnerabilities (USN-6045-1)

high Nessus Plugin ID 174804

Synopsis

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

Description

The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6045-1 advisory.

It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. (CVE-2023-1829)

Gwnaun Jung discovered that the SFB packet scheduling implementation in the Linux kernel contained a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3586)

Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-4095)

It was discovered that the TIPC protocol implementation in the Linux kernel did not properly validate the queue of socket buffers (skb) when handling certain UDP packets. A remote attacker could use this to cause a denial of service. (CVE-2023-1390)

It was discovered that the Xircom PCMCIA network device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-1670)

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.
