Ubuntu 22.04 LTS Linux Kernel Important Security Flaws USN-8575-2

ubuntu

July 23, 2026

Ubuntu has released updates for its Linux kernel to address multiple security vulnerabilities affecting Ubuntu 20.04 and 22.04 LTS, requiring users to reboot after installation.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-aws: Linux kernel for Amazon Web Services (AWS) systems

- linux-aws-fips: Linux kernel for Amazon Web Services (AWS) systems with FIPS

- linux-fips: Linux kernel with FIPS

- linux-ibm: Linux kernel for IBM cloud systems

- linux-nvidia: Linux kernel for NVIDIA systems

- linux-aws-5.15: Linux kernel for Amazon Web Services (AWS) systems

Details:

Maxim Suhanov discovered that the NTFS file system implementation in the

Linux kernel did not properly validate file name length in certain

situations, leading to an out-of-bounds read. An attacker could use this to

construct a malicious NTFS image that, when mounted and operated on, could

expose sensitive information (kernel memory). (CVE-2023-45896)

It was discovered that some AMD processors did not properly clear data in

the floating point divider unit during speculative execution. A local

attacker could use this to expose sensitive information. (CVE-...

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.
