[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-7021-3 --- # USN-7021-3: Linux kernel vulnerabilities Publication date 26 September 2024 Overview Several security issues were fixed in the Linux kernel. Releases [22.04 LTS](https://ubuntu.com/security/notices?release=jammy) [20.04 LTS](https://ubuntu.com/security/notices?release=focal) --- Open side navigation ## Packages * [linux-lowlatency](https://ubuntu.com/security/cves?package=linux-lowlatency) - Linux low latency kernel * [linux-lowlatency-hwe-5.15](https://ubuntu.com/security/cves?package=linux-lowlatency-hwe-5.15) - Linux low latency kernel ## Details Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: * GPU drivers; * BTRFS file system; * F2FS file system; * GFS2 file system; * BPF subsystem; * Netfilter; * RxRPC session sockets; * Integrity Measurement Architecture(IMA) framework ## Update instructions After a standard system update you need to reboot your computer to make all the necessary changes. [Learn more about how to get the fixes.](https://ubuntu.com/security/cves/about#security) 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. The problem can be corrected by updating your system to the following package versions: | Ubuntu Release | Package Version | | --- | --- | | 22.04 LTS jammy | [linux-image-5.15.0-122-lowlatency](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency) –  [5.15.0-122.132](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency/5.15.0-122.132) | | | | [linux-image-5.15.0-122-lowlatency-64k](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency) –  [5.15.0-122.132](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency/5.15.0-122.132) | | | | [linux-image-lowlatency](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency) –  [5.15.0.122.111](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency/5.15.0.122.111) | | | | [linux-image-lowlatency-64k](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency) –  [5.15.0.122.111](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency/5.15.0.122.111) | | | | 20.04 LTS focal | [linux-image-5.15.0-122-lowlatency](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency-hwe-5.15) –  [5.15.0-122.132~20.04.1](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency-hwe-5.15/5.15.0-122.132~20.04.1) | | | | [linux-image-5.15.0-122-lowlatency-64k](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency-hwe-5.15) –  [5.15.0-122.132~20.04.1](https://launchpad.net/ubuntu/+source/linux-signed-lowlatency-hwe-5.15/5.15.0-122.132~20.04.1) | | | | [linux-image-lowlatency-64k-hwe-20.04](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency-hwe-5.15) –  [5.15.0.122.132~20.04.1](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency-hwe-5.15/5.15.0.122.132~20.04.1) | | | | [linux-image-lowlatency-hwe-20.04](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency-hwe-5.15) –  [5.15.0.122.132~20.04.1](https://launchpad.net/ubuntu/+source/linux-meta-lowlatency-hwe-5.15/5.15.0.122.132~20.04.1) | | | --- ### Reduce your security exposure Ubuntu Pro provides ten-year security coverage to 25,000+ packages in Main and Universe repositories, and it is free for up to five machines.
