An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: * ARM64 architecture; * PowerPC architecture; * x86 architecture; * ACPI drivers; * Serial ATA and Parallel ATA drivers; * Drivers core; * ATA over ethernet (AOE) driver; * Network block device driver; * Bus devices; * Clock framework and drivers; * Hardware crypto device drivers; * DMA engine subsystem; * EDAC drivers; * GPU drivers; * HID subsystem; * InfiniBand drivers; * Input Device (Miscellaneous) drivers; * Multiple devices driver; * Media drivers; * VMware VMCI Driver; * MMC subsystem; * MTD block device drivers; * Network drivers; * Pin controllers subsystem; * x86 platform drivers; * PTP clock... --- 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-5.15.0-1096-azure](https://launchpad.net/ubuntu/+source/linux-signed-azure) –  [5.15.0-1096.105](https://launchpad.net/ubuntu/+source/linux-signed-azure/5.15.0-1096.105) | | | | [linux-image-azure-5.15](https://launchpad.net/ubuntu/+source/linux-meta-azure) –  [5.15.0.1096.94](https://launchpad.net/ubuntu/+source/linux-meta-azure/5.15.0.1096.94) | | | | [linux-image-azure-lts-22.04](https://launchpad.net/ubuntu/+source/linux-meta-azure) –  [5.15.0.1096.94](https://launchpad.net/ubuntu/+source/linux-meta-azure/5.15.0.1096.94) | | | --- ### 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.
