Ubuntu 6774-1: Linux kernel Security Advisory Updates
Summary
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 23.10 - 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-laptop: Linux kernel for Lenovo X13s ARM laptops - linux-lowlatency: Linux low latency kernel - linux-oracle: Linux kernel for Oracle Cloud systems - linux-raspi: Linux kernel for Raspberry Pi systems - linux-starfive: Linux kernel for StarFive processors - linux-aws-6.5: Linux kernel for Amazon Web Services (AWS) systems - linux-azure-6.5: Linux kernel for Microsoft Azure cloud systems - linux-gcp-6.5: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe-6.5: Linux hardware enablement (HWE) kernel - linux-lowlatency-hwe-6.5: Linux low latency kernel - linux-nvidia-6.5: Linux kernel for NVIDIA systems - linux-oem-6.5: Linux kernel for OEM systems - linux-oracle-6.5: Linux kernel for Oracle Cloud systems - linux-starfive-6.5: Linux kernel for StarFive processors Details: Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-47233) Sander Wiebing, Alvise de Faveri Tron, Herbert Bos, and Cristiano Giuffrida discovered that the Linux kernel mitigations for the initial Branch History Injection vulnerability (CVE-2022-0001) were insufficient for Intel processors. A local attacker could potentially use this to expose sensitive information. (CVE-2024-2201) 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: - Hardware random number generator core; - Ext4 file system; - JFS file system; - Bluetooth subsystem; - Networking core; - IPv4 networking; - Logical Link layer; - Netlink; - Tomoyo security module; (CVE-2024-26704, CVE-2023-52615, CVE-2024-26805, CVE-2023-52604, CVE-2024-26614, CVE-2023-52602, CVE-2024-26635, CVE-2024-26622, CVE-2023-52601, CVE-2024-26801)

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.
