Ubuntu 22.04 LTS USN-6795-1 Critical: Kernel Denial Of Service Threats

Dist Ubuntu Esm H88
The latest Ubuntu 22.04 LTS security advisory reveals critical kernel vulnerabilities, urging immediate updates to secure systems and protect user data.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-intel-iotg: Linux kernel for Intel IoT platforms

Details:

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux

kernel contained a race condition during device removal, leading to a use-

after-free vulnerability. A physically proximate attacker could possibly

use this to cause a denial of service (system crash). (CVE-2023-47233)

It was discovered that the Open vSwitch implementation in the Linux kernel

could overflow its stack during recursive action operations under certain

conditions. A local attacker could use this to cause a denial of service

(system crash). (CVE-2024-1151)

Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida

discovered that the Linux kernel mitigations for the initial Branch History

Injection vulnerability (CVE-2022-0001) were insufficient for Intel

processors. A local attacker could potentially use this to e...

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS
   linux-image-5.15.0-1057-intel-iotg  5.15.0-1057.63
   linux-image-intel-iotg          5.15.0.1057.57

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
