[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-6766-3 --- # USN-6766-3: Linux kernel (AWS) vulnerabilities Publication date 20 May 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-aws](https://ubuntu.com/security/cves?package=linux-aws) - Linux kernel for Amazon Web Services (AWS) systems * [linux-aws-5.15](https://ubuntu.com/security/cves?package=linux-aws-5.15) - Linux kernel for Amazon Web Services (AWS) systems ## Details 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](https://ubuntu.com/security/CVE-2024-1151)) Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability ([CVE-2022-0001](https://ubuntu.com/security/CVE-2022-0001)) were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information. ([CVE-2024-2201](https://ubuntu.com/security/CVE-2024-2201)) Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system crash).

[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-5.15.0-1061-aws](https://launchpad.net/ubuntu/+source/linux-signed-aws) –  [5.15.0-1061.67](https://launchpad.net/ubuntu/+source/linux-signed-aws/5.15.0-1061.67) | | | | [linux-image-aws-lts-22.04](https://launchpad.net/ubuntu/+source/linux-meta-aws) –  [5.15.0.1061.61](https://launchpad.net/ubuntu/+source/linux-meta-aws/5.15.0.1061.61) | | | | 20.04 LTS focal | [linux-image-5.15.0-1061-aws](https://launchpad.net/ubuntu/+source/linux-signed-aws-5.15) –  [5.15.0-1061.67~20.04.1](https://launchpad.net/ubuntu/+source/linux-signed-aws-5.15/5.15.0-1061.67~20.04.1) | | | | [linux-image-aws](https://launchpad.net/ubuntu/+source/linux-meta-aws-5.15) –  [5.15.0.1061.67~20.04.1](https://launchpad.net/ubuntu/+source/linux-meta-aws-5.15/5.15.0.1061.67~20.04.1) | | | --- ### 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.
