[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-6893-3 --- # USN-6893-3: Linux kernel vulnerabilities Publication date 23 July 2024 Overview Several security issues were fixed in the Linux kernel. Releases [24.04 LTS](https://ubuntu.com/security/notices?release=noble) --- Open side navigation ## Packages * [linux-aws](https://ubuntu.com/security/cves?package=linux-aws) - Linux kernel for Amazon Web Services (AWS) systems ## Details It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. ([CVE-2024-24857](https://ubuntu.com/security/CVE-2024-24857), [CVE-2024-24858](https://ubuntu.com/security/CVE-2024-24858), [CVE-2024-24859](https://ubuntu.com/security/CVE-2024-24859)) 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: * ARM64 architecture; * RISC-V architecture; * S390 architecture; * x86 architecture; * Block layer subsystem; * Compute Acceleration Framework; * Accessibility subsystem; * Android drivers; * Drivers core; * Bluetooth drivers; * Clock framework and drivers; * Data acquisition framework and... --- Show more ## 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 | | --- | --- | | 24.04 LTS noble | [linux-image-6.8.0-1011-aws](https://launchpad.net/ubuntu/+source/linux-signed-aws) –  [6.8.0-1011.12](https://launchpad.net/ubuntu/+source/linux-signed-aws/6.8.0-1011.12) | | | | [linux-image-aws](https://launchpad.net/ubuntu/+source/linux-meta-aws) –  [6.8.0-1011.12](https://launchpad.net/ubuntu/+source/linux-meta-aws/6.8.0-1011.12) | | | --- ### 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.
