========================================================================== Ubuntu Security Notice USN-6174-1 June 16, 2023 linux-oem-5.17 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-oem-5.17: Linux kernel for OEM systems Details: 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) It was discovered that the Human Interface Device (HID) support driver in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-1073) It was discovered that the NTFS file system implementation in the Linux kernel did not properly handle a loop termination condition, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-26606) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.17.0-1033-oem 5.17.0-1033.34 linux-image-oem-22.04 5.17.0.1033.31 linux-image-oem-22.04a 5.17.0.1033.31 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.
