Ubuntu 6972-1: Linux kernel Security Advisory Updates
Summary
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel - linux-gcp-4.15: Linux kernel for Google Cloud Platform (GCP) systems - linux-kvm: Linux kernel for cloud environments - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems - linux-hwe: Linux hardware enablement (HWE) kernel Details: Yuxuan Hu discovered that the Bluetooth RFCOMM protocol driver in the Linux Kernel contained a race condition, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service (system crash). (CVE-2024-22099) It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a denial of service (system crash). (CVE-2024-24860) 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: - SuperH RISC architecture; - User-Mode Linux (UML); - GPU drivers; - MMC subsystem; - Network drivers; - PHY drivers; - Pin controllers subsystem; - Xen hypervisor drivers; - GFS2 file system; - Core kernel; - Bluetooth subsystem; - IPv4 networking; - IPv6 networking; - HD-audio driver; - ALSA SH drivers; (CVE-2024-26903, CVE-2024-35835, CVE-2023-52644, CVE-2024-39292, CVE-2024-36940, CVE-2024-26600, CVE-2023-52629, CVE-2024-35955, CVE-2023-52760, CVE-2023-52806, CVE-2024-39484, CVE-2024-26679, CVE-2024-26654, CVE-2024-36901, CVE-2024-26687, CVE-2023-52470)
Update Instructions
The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS linux-image-4.15.0-1155-kvm 4.15.0-1155.160 Available with Ubuntu Pro linux-image-4.15.0-1165-gcp 4.15.0-1165.182 Available with Ubuntu Pro linux-image-4.15.0-228-generic 4.15.0-228.240 Available with Ubuntu Pro linux-image-4.15.0-228-lowlatency 4.15.0-228.240 Available with Ubuntu Pro linux-image-gcp-lts-18.04 4.15.0.1165.178 Available with Ubuntu Pro linux-image-generic 4.15.0.228.212 Available with Ubuntu Pro linux-image-kvm 4.15.0.1155.146 Available with Ubuntu Pro linux-image-lowlatency 4.15.0.228.212 Available with Ubuntu Pro linux-image-virtual 4.15.0.228.212 Available with Ubuntu Pro Ubuntu 16.04 LTS linux-image-4.15.0-1165-gcp 4.15.0-1165.182~16.04.1 Available with Ubuntu Pro linux-image-4.15.0-228-generic 4.15.0-228.240~16.04.1 Available with Ubuntu Pro linux-image-4.15.0-228-lowlatency 4.15.0-228.240~16.04.1 Available with Ubuntu Pro linux-image-gcp 4.15.0.1165.182~16.04.1 Available with Ubuntu Pro linux-image-generic-hwe-16.04 4.15.0.228.240~16.04.1 Available with Ubuntu Pro linux-image-gke 4.15.0.1165.182~16.04.1 Available with Ubuntu Pro linux-image-lowlatency-hwe-16.04 4.15.0.228.240~16.04.1 Available with Ubuntu Pro linux-image-oem 4.15.0.228.240~16.04.1 Available with Ubuntu Pro linux-image-virtual-hwe-16.04 4.15.0.228.240~16.04.1 Available with Ubuntu Pro 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.
