Ubuntu 22.04 LTS: USN-6900-1 Critical: Kernel Denial Of Service Issues

ubuntu
Calendar Grey July 17, 2024
Dist Ubuntu Esm H88
Crucial kernel versions for Ubuntu address major vulnerabilities that could result in service interruption and potential security breaches.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-hwe-6.5: Linux hardware enablement (HWE) kernel

Details:

It was discovered that the ATA over Ethernet (AoE) driver in the Linux

kernel contained a race condition, leading to a use-after-free

vulnerability. An attacker could use this to cause a denial of service or

possibly execute arbitrary code. (CVE-2023-6270)

It was discovered that the HugeTLB file system component of the Linux

Kernel contained a NULL pointer dereference vulnerability. A privileged

attacker could possibly use this to to cause a denial of service.

(CVE-2024-0841)

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)

Gui-Dong Han discovered that the software RAID driver in the Linux kernel

contained a race condition, leading to...

Update Instructions

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

Ubuntu 22.04 LTS
  linux-image-6.5.0-44-generic    6.5.0-44.44~22.04.1
  linux-image-6.5.0-44-generic-64k  6.5.0-44.44~22.04.1
  linux-image-generic-64k-hwe-22.04  6.5.0.44.44~22.04.1
  linux-image-generic-hwe-22.04   6.5.0.44.44~22.04.1
  linux-image-virtual-hwe-22.04   6.5.0.44.44~22.04.1

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.
