Software Description: - linux-oem-5.17: Linux kernel for OEM systems Details: It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly handle some error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1679) Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle guest TLB mapping invalidation requests in some situations. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1789) Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM hypervisor implementation in the Linux kernel did not properly handle an illegal instruction in a guest, resulting in a null pointer dereference. An attacker in a guest VM could use this to cause a denial of service (system crash) in the host OS. (CVE-2022-1852) Gerald Lee discovered that the NTFS file system implementation in the Linux kernel did not properly handle certain error conditions, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2022-1973) It was discovered that the netfilter subsystem in the Linux kernel contained a buffer overflow in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2078) It was discovered that some Intel processors did not completely perform cleanup actions on multi-core shared buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21123) It was discovered that some Intel processors did not completely perform cleanup actions on microarchitectural fill buffers. A local attacker could possibly use this to expose sensitive information. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21166) It was discovered that the virtio RPMSG bus driver in the Linux kernel contained a double-free vulnerability in certain error conditions. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-34494, CVE-2022-34495) Minh Yuan discovered that the floppy disk driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1652) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-5.17.0-1013-oem 5.17.0-1013.14 linux-image-oem-22.04 5.17.0.1013.12 linux-image-oem-22.04a 5.17.0.1013.12 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.
