[USN-6777-3] Linux kernel (GCP) vulnerabilities
== Ubuntu Security Notice USN-6777-3 May 21, 2024 linux-gcp vulnerabilities == A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems 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) 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: - Block layer subsystem; - Userspace I/O drivers; - Ceph distributed file system; - Ext4 file system; - JFS file system; - NILFS2 file system; - Bluetooth subsystem; - Networking core; - IPv4 networking; - IPv6 networking; - Logical Link layer; - MAC80211 subsystem; - Netlink; - NFC subsystem; - Tomoyo security module; (CVE-2023-52524, CVE-2023-52530, CVE-2023-52601, CVE-2023-52439, CVE-2024-26635, CVE-2023-52602, CVE-2024-26614, CVE-2024-26704, CVE-2023-52604, CVE-2023-52566, CVE-2021-46981, CVE-2024-26622, CVE-2024-26735, CVE-2024-26805, CVE-2024-26801, CVE-2023-52583) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS linux-image-4.15.0-1162-gcp 4.15.0-1162.179~16.04.1 Available with Ubuntu Pro linux-image-gcp 4.15.0.1162.179~16.04.1 Available with Ubuntu Pro linux-image-gke 4.15.0.1162.179~16.04.1 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.
