Security vulnerabilities in the Linux kernel of Ubuntu 20.04 LTS have been fixed. For detailed insights and necessary actions, check the official security advisories
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-ibm-5.15: Linux kernel for IBM cloud systems

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 Atheros 802.11ac wireless driver did not

properly validate certain data structures, leading to a NULL pointer

dereference. An attacker could possibly use this to cause a denial of

service. (CVE-2023-7042)

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 Intel Data Streaming and Intel Analytics

Accelerator drivers in the Linux kernel allow...

Update Instructions

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

Ubuntu 20.04 LTS
   linux-image-5.15.0-1057-ibm     5.15.0-1057.60~20.04.1
   linux-image-ibm                 5.15.0.1057.60~20.04.1

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.
