========================================================================== Ubuntu Security Notice USN-5754-1 December 01, 2022
linux, linux-aws, linux-gcp, linux-ibm, linux-kvm, linux-lowlatency, linux-oracle, linux-raspi vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.10
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-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-ibm: Linux kernel for IBM cloud systems - linux-kvm: Linux kernel for cloud environments - linux-lowlatency: Linux low latency kernel - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems
Details:
It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43945)
It was discovered that a memory leak existed in the IPv6 implementation of the Linux kernel. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3524)
It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, 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-2022-3564)
It was discovered that the ISDN implementation of the Linux kernel contained a use-after-free vulnerability. A privileged user could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3565)
It was discovered that the TCP implementation in the Linux kernel contained a data race condition. An attacker could possibly use this to cause undesired behaviors. (CVE-2022-3566)
It was discovered that the IPv6 implementation in the Linux kernel contained a data race condition. An attacker could possibly use this to cause undesired behaviors. (CVE-2022-3567)
It was discovered that the Realtek RTL8152 USB Ethernet adapter driver in the Linux kernel did not properly handle certain error conditions. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (memory exhaustion). (CVE-2022-3594)
It was discovered that a null pointer dereference existed in the NILFS2 file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3621)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.10: linux-image-5.19.0-1009-raspi 5.19.0-1009.16 linux-image-5.19.0-1009-raspi-nolpae 5.19.0-1009.16 linux-image-5.19.0-1012-lowlatency 5.19.0-1012.13 linux-image-5.19.0-1012-lowlatency-64k 5.19.0-1012.13 linux-image-5.19.0-1013-gcp 5.19.0-1013.14 linux-image-5.19.0-1013-ibm 5.19.0-1013.14 linux-image-5.19.0-1013-kvm 5.19.0-1013.14 linux-image-5.19.0-1013-oracle 5.19.0-1013.14 linux-image-5.19.0-1014-aws 5.19.0-1014.15 linux-image-5.19.0-26-generic 5.19.0-26.27 linux-image-5.19.0-26-generic-64k 5.19.0-26.27 linux-image-5.19.0-26-generic-lpae 5.19.0-26.27 linux-image-aws 5.19.0.1014.11 linux-image-gcp 5.19.0.1013.10 linux-image-generic 5.19.0.26.23 linux-image-generic-64k 5.19.0.26.23 linux-image-generic-lpae 5.19.0.26.23 linux-image-ibm 5.19.0.1013.10 linux-image-kvm 5.19.0.1013.10 linux-image-lowlatency 5.19.0.1012.9 linux-image-lowlatency-64k 5.19.0.1012.9 linux-image-oracle 5.19.0.1013.10 linux-image-raspi 5.19.0.1009.8 linux-image-raspi-nolpae 5.19.0.1009.8 linux-image-virtual 5.19.0.26.23
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.
