Ubuntu 22.04 LTS USN-6766-2 Critical: Linux Kernel Denial Of Service

ubuntu
Calendar Grey May 15, 2024
Dist Ubuntu Esm H88
Significant vulnerabilities resolved in the Linux kernel for Ubuntu, tackling denial of service threats and risks of sensitive data leakage.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-raspi: Linux kernel for Raspberry Pi systems

- linux-hwe-5.15: Linux hardware enablement (HWE) kernel

Details:

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 expose sensitive

information. (CVE-2024-2201)

Chenyuan Yang discovered that the RDS Protocol implementation in the Linux

kernel contained an out-of-bounds read vulnerability. An attacker could use

this to possibly cause a denial of service...

Update Instructions

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

Ubuntu 22.04 LTS
   linux-image-5.15.0-1054-raspi   5.15.0-1054.57
   linux-image-raspi               5.15.0.1054.52
   linux-image-raspi-nolpae        5.15.0.1054.52

Ubuntu 20.04 LTS
   linux-image-5.15.0-106-generic  5.15.0-106.116~20.04.1
   linux-image-5.15.0-106-generic-64k  5.15.0-106.116~20.04.1
   linux-image-5.15.0-106-generic-lpae  5.15.0-106.116~20.04.1
   linux-image-generic-64k-hwe-20.04  5.15.0.106.116~20.04.1
   linux-image-generic-hwe-20.04   5.15.0.106.116~20.04.1
   linux-image-generic-lpae-hwe-20.04  5.15.0.106.116~20.04.1
   linux-image-oem-20.04           5.15.0.106.116~20.04.1
   linux-image-oem-20.04b          5.15.0.106.116~20.04.1
   linux-image-oem-20.04c          5.15.0.106.116~20.04.1
   linux-image-oem-20.04d          5.15.0.106.116~20.04.1
   linux-image-virtual-hwe-20.04   5.15.0.106.116~20.04.1

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.
