==========================================================================Ubuntu Security Notice USN-6743-2April 22, 2024linux-lowlatency-hwe-6.5 vulnerabilities==========================================================================A security issue affects these releases of Ubuntu and its derivatives:- Ubuntu 22.04 LTSSummary:Several security issues were fixed in the Linux kernel.Software Description:- linux-lowlatency-hwe-6.5: Linux low latency kernelDetails:Several security issues were discovered in the Linux kernel.An attacker could possibly use these to compromise the system.This update corrects flaws in the following subsystems: - JFS file system; - BPF subsystem; - Netfilter;(CVE-2023-52600, CVE-2024-26589, CVE-2024-26591, CVE-2024-26581,CVE-2023-52603)Update instructions:The problem can be corrected by updating your system to the followingpackage versions:Ubuntu 22.04 LTS: linux-image-6.5.0-28-lowlatency 6.5.0-28.29.1~22.04.1 linux-image-6.5.0-28-lowlatency-64k 6.5.0-28.29.1~22.04.1 linux-image-lowlatency-64k-hwe-22.04 6.5.0.28.29.1~22.04.1 linux-image-lowlatency-hwe-22.04 6.5.0.28.29.1~22.04.1After 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-6743-2 https://ubuntu.com/security/notices/USN-6743-1 CVE-2023-52600, CVE-2023-52603, CVE-2024-26581, CVE-2024-26589, CVE-2024-26591Package Information: https://launchpad.net/ubuntu/+source/linux-lowlatency-hwe-6.5/6.5.0-28.29.1~22.04.1Related news
Red Hat Security Advisory 2024-4831-03 - An update for kernel-rt is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.
Red Hat Security Advisory 2024-4823-03 - An update for kernel is now available for Red Hat Enterprise Linux 9.2 Extended Update Support. Issues addressed include denial of service, double free, and information leakage vulnerabilities.
It was discovered that the ATA over Ethernet (AoE) driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the AppleTalk networking subsystem of 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. Various other issues were also addressed.
Ubuntu Security Notice 6743-3 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
Ubuntu Security Notice 6742-2 - Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials. A physically proximate attacker placed between two Bluetooth devices could use this to subsequently impersonate one of the paired devices. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
Ubuntu Security Notice 6725-2 - Chih-Yen Chang discovered that the KSMBD implementation in the Linux kernel did not properly validate certain data structure fields when parsing lease contexts, leading to an out-of-bounds read vulnerability. A remote attacker could use this to cause a denial of service or possibly expose sensitive information. Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6688-1 - Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a guest VM could possibly use this to cause a denial of service. It was discovered that the Habana's AI Processors driver in the Linux kernel did not properly initialize certain data structures before passing them to user space. A local attacker could use this to expose sensitive information.
