========================================================================== Ubuntu Security Notice USN-6938-1 July 31, 2024 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 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-kvm: Linux kernel for cloud environments - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty Details: It was discovered that the device input subsystem in the Linux kernel did not properly handle the case when an event code falls outside of a bitmap. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-48619) 黄思聪 discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46343) It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service. (CVE-2024-24857, CVE-2024-24858, CVE-2024-24859) Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device volume management subsystem did not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this to cause a denial of service (system crash). (CVE-2024-25739) 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: - GPU drivers; - HID subsystem; - I2C subsystem; - Input Device Drivers (Mouse); - MTD block device drivers; - Network drivers; - TTY drivers; - USB subsystem; - File systems infrastructure; - F2FS file system; - SMB network file system; - BPF subsystem; - B.A.T.M.A.N. meshing protocol; - Bluetooth subsystem; - IPv4 networking; - IPv6 networking; - Netfilter; - Unix domain sockets; - Wireless networking; (CVE-2024-26901, CVE-2021-46932, CVE-2024-26857, CVE-2024-26882, CVE-2024-26934, CVE-2023-52449, CVE-2024-35982, CVE-2021-46933, CVE-2023-52620, CVE-2023-52444, CVE-2024-26923, CVE-2023-52469, CVE-2024-26886, CVE-2024-36902, CVE-2023-52436, CVE-2024-36016, CVE-2024-26884, CVE-2021-46960, CVE-2021-47194, CVE-2023-52752, CVE-2024-27020, CVE-2024-26840, CVE-2024-35997, CVE-2024-35984, CVE-2024-35978) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS linux-image-4.4.0-1135-kvm 4.4.0-1135.145 Available with Ubuntu Pro linux-image-4.4.0-1172-aws 4.4.0-1172.187 Available with Ubuntu Pro linux-image-4.4.0-257-generic 4.4.0-257.291 Available with Ubuntu Pro linux-image-4.4.0-257-lowlatency 4.4.0-257.291 Available with Ubuntu Pro linux-image-aws 4.4.0.1172.176 Available with Ubuntu Pro linux-image-generic 4.4.0.257.263 Available with Ubuntu Pro linux-image-generic-lts-xenial 4.4.0.257.263 Available with Ubuntu Pro linux-image-kvm 4.4.0.1135.132 Available with Ubuntu Pro linux-image-lowlatency 4.4.0.257.263 Available with Ubuntu Pro linux-image-lowlatency-lts-xenial 4.4.0.257.263 Available with Ubuntu Pro linux-image-virtual 4.4.0.257.263 Available with Ubuntu Pro linux-image-virtual-lts-xenial 4.4.0.257.263 Available with Ubuntu Pro Ubuntu 14.04 LTS linux-image-4.4.0-1134-aws 4.4.0-1134.140 Available with Ubuntu Pro linux-image-4.4.0-257-generic 4.4.0-257.291~14.04.1 Available with Ubuntu Pro linux-image-4.4.0-257-lowlatency 4.4.0-257.291~14.04.1 Available with Ubuntu Pro linux-image-aws 4.4.0.1134.131 Available with Ubuntu Pro linux-image-generic-lts-xenial 4.4.0.257.291~14.04.1 Available with Ubuntu Pro linux-image-lowlatency-lts-xenial 4.4.0.257.291~14.04.1 Available with Ubuntu Pro linux-image-virtual-lts-xenial 4.4.0.257.291~14.04.1 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.
