========================================================================== Ubuntu Security Notice USN-5911-1 March 02, 2023 linux, linux-aws, linux-azure, linux-gcp, linux-hwe-5.19, linux-ibm, linux-lowlatency, linux-oracle vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.10 - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-azure: Linux kernel for Microsoft Azure Cloud systems - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-lowlatency: Linux low latency kernel - linux-oracle: Linux kernel for Oracle Cloud systems - linux-hwe-5.19: Linux hardware enablement (HWE) kernel Details: It was discovered that the Upper Level Protocol (ULP) subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, 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-2023-0461) Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-0179) It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3169) Maxim Levitsky discovered that the KVM nested virtualization (SVM) implementation for AMD processors in the Linux kernel did not properly handle nested shutdown execution. An attacker in a guest vm could use this to cause a denial of service (host kernel crash) (CVE-2022-3344) Gwangun Jung discovered a race condition in the IPv4 implementation in the Linux kernel when deleting multipath routes, resulting in an out-of-bounds read. An attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-3435) It was discovered that a race condition existed in the Kernel Connection Multiplexor (KCM) socket implementation in the Linux kernel when releasing sockets in certain situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3521) It was discovered that the Netronome Ethernet driver in the Linux kernel contained 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-2022-3545) 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. (CVE-2022-4139) It was discovered that the NFSD implementation in the Linux kernel contained a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-4379) It was discovered that a race condition existed in the x86 KVM subsystem implementation in the Linux kernel when nested virtualization and the TDP MMU are enabled. An attacker in a guest vm could use this to cause a denial of service (host OS crash). (CVE-2022-45869) It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate the number of channels, leading to an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-47518) It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate specific attributes, leading to an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-47519) It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate offsets, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash). (CVE-2022-47520) It was discovered that the Atmel WILC1000 driver in the Linux kernel did not properly validate specific attributes, leading to a heap-based buffer overflow. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-47521) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.10: linux-image-5.19.0-1018-gcp 5.19.0-1018.20 linux-image-5.19.0-1018-ibm 5.19.0-1018.20 linux-image-5.19.0-1018-lowlatency 5.19.0-1018.19 linux-image-5.19.0-1018-lowlatency-64k 5.19.0-1018.19 linux-image-5.19.0-1018-oracle 5.19.0-1018.21 linux-image-5.19.0-1020-aws 5.19.0-1020.21 linux-image-5.19.0-1021-azure 5.19.0-1021.22 linux-image-5.19.0-35-generic 5.19.0-35.36 linux-image-5.19.0-35-generic-64k 5.19.0-35.36 linux-image-5.19.0-35-generic-lpae 5.19.0-35.36 linux-image-aws 5.19.0.1020.17 linux-image-azure 5.19.0.1021.17 linux-image-gcp 5.19.0.1018.15 linux-image-generic 5.19.0.35.32 linux-image-generic-64k 5.19.0.35.32 linux-image-generic-lpae 5.19.0.35.32 linux-image-ibm 5.19.0.1018.15 linux-image-lowlatency 5.19.0.1018.15 linux-image-lowlatency-64k 5.19.0.1018.15 linux-image-oracle 5.19.0.1018.15 linux-image-virtual 5.19.0.35.32 Ubuntu 22.04 LTS: linux-image-5.19.0-35-generic 5.19.0-35.36~22.04.1 linux-image-5.19.0-35-generic-64k 5.19.0-35.36~22.04.1 linux-image-5.19.0-35-generic-lpae 5.19.0-35.36~22.04.1 linux-image-generic-64k-hwe-22.04 5.19.0.35.36~22.04.10 linux-image-generic-hwe-22.04 5.19.0.35.36~22.04.10 linux-image-generic-lpae-hwe-22.04 5.19.0.35.36~22.04.10 linux-image-virtual-hwe-22.04 5.19.0.35.36~22.04.10 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.
