Ubuntu 20.04 LTS: USN-7413-1 Critical: Linux Kernel Denial of Service

ubuntu
Calendar Grey April 3, 2025
Dist Ubuntu Esm H88
A multitude of security updates for the Linux kernel on Ubuntu, bolstering system defenses against denial-of-service and potential code execution vulnerabilities.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-iot: Linux kernel for IoT platforms

Details:

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not

properly handle certain error conditions, leading to a NULL pointer

dereference. A local attacker could possibly trigger this vulnerability to

cause a denial of service. (CVE-2022-38096)

Ye Zhang and Nicolas Wu discovered that the io_uring subsystem in the Linux

kernel did not properly handle locking for rings with IOPOLL, leading to a

double-free vulnerability. A local attacker could use this to cause a

denial of service (system crash) or possibly execute arbitrary code.

(CVE-2023-21400)

Chenyuan Yang discovered that the CEC driver 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-2024-23848)

Update Instructions

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

Ubuntu 20.04 LTS
   linux-image-5.4.0-1048-iot      5.4.0-1048.51

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.
