[Ubuntu Security Notices](https://ubuntu.com/security/notices) 2. USN-6085-1 --- # USN-6085-1: Linux kernel (Raspberry Pi) vulnerabilities Publication date 17 May 2023 Overview Several security issues were fixed in the Linux kernel. Releases [22.04 LTS](https://ubuntu.com/security/notices?release=jammy) --- Open side navigation ## Packages * [linux-raspi](https://ubuntu.com/security/cves?package=linux-raspi) - Linux kernel for Raspberry Pi systems ## Details It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. ([CVE-2022-27672](https://ubuntu.com/security/CVE-2022-27672)) Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). ([CVE-2022-3707](https://ubuntu.com/security/CVE-2022-3707)) Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information (kernel memory). ([CVE-2023-0459](https://ubuntu.com/security/CVE-2023-0459)) It was discovered that the TLS subsystem in the... --- 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 | | --- | --- | | 22.04 LTS jammy | [linux-image-raspi-nolpae](https://launchpad.net/ubuntu/+source/linux-meta-raspi) –  [5.15.0.1029.26](https://launchpad.net/ubuntu/+source/linux-meta-raspi/5.15.0.1029.26) | | | | [linux-image-raspi](https://launchpad.net/ubuntu/+source/linux-meta-raspi) –  [5.15.0.1029.26](https://launchpad.net/ubuntu/+source/linux-meta-raspi/5.15.0.1029.26) | | | | [linux-image-5.15.0-1029-raspi-nolpae](https://launchpad.net/ubuntu/+source/linux-raspi) –  [5.15.0-1029.31](https://launchpad.net/ubuntu/+source/linux-raspi/5.15.0-1029.31) | | | | [linux-image-5.15.0-1029-raspi](https://launchpad.net/ubuntu/+source/linux-raspi) –  [5.15.0-1029.31](https://launchpad.net/ubuntu/+source/linux-raspi/5.15.0-1029.31) | | | --- ### 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.
