Ubuntu Security Notice 6089-1 - It was discovered that the Intel i915 graphics driver in the Linux kernel did not perform a GPU TLB flush in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.
==========================================================================Ubuntu Security Notice USN-6089-1May 18, 2023linux-oem-6.0 vulnerability==========================================================================A security issue affects these releases of Ubuntu and its derivatives:- Ubuntu 22.04 LTSSummary:The system could be made to crash or run programs as an administrator.Software Description:- linux-oem-6.0: Linux kernel for OEM systemsDetails:It was discovered that the Intel i915 graphics driver in the Linux kerneldid not perform a GPU TLB flush in some situations. A local attacker coulduse this to cause a denial of service or possibly execute arbitrary code.Update instructions:The problem can be corrected by updating your system to the followingpackage versions:Ubuntu 22.04 LTS: linux-image-6.0.0-1016-oem 6.0.0-1016.16 linux-image-oem-22.04b 6.0.0.1016.16After a standard system update you need to reboot your computer to makeall the necessary changes.ATTENTION: Due to an unavoidable ABI change the kernel updates havebeen given a new version number, which requires you to recompile andreinstall 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 performthis as well.References: https://ubuntu.com/security/notices/USN-6089-1 CVE-2022-4139Package Information: https://launchpad.net/ubuntu/+source/linux-oem-6.0/6.0.0-1016.16Related news
Ubuntu Security Notice 6124-1 - Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in the netfilter subsystem of the Linux kernel when processing batch requests, leading to a use-after-free vulnerability.
