========================================================================== Ubuntu Security Notice USN-7183-1 January 06, 2025 linux, 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-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty Details: Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-confusion error. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-12351) Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate remote attacker could use this to expose sensitive information (kernel memory). (CVE-2020-12352) Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490) Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-36402) Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during device removal. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-35827) 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; - I2C subsystem; - Network drivers; - Pin controllers subsystem; - TTY drivers; - USB Mass Storage drivers; - Framebuffer layer; - Ext4 file system; - File systems infrastructure; - Bluetooth subsystem; - Kernel init infrastructure; - DMA mapping infrastructure; - Memory management; - 9P file system network protocol; - IPv4 networking; - IPv6 networking; - Logical Link layer; - MAC80211 subsystem; - Netfilter; - NFC subsystem; - Phonet protocol; - Network traffic control; - Wireless networking; (CVE-2024-44947, CVE-2023-52594, CVE-2024-35886, CVE-2024-38633, CVE-2023-52509, CVE-2024-26625, CVE-2024-36946, CVE-2024-45021, CVE-2024-36270, CVE-2021-47118, CVE-2024-43884, CVE-2024-36941, CVE-2024-38619, CVE-2021-47501, CVE-2024-49967, CVE-2024-42090, CVE-2024-40912, CVE-2024-36968, CVE-2024-53057, CVE-2023-52507, CVE-2024-42101, CVE-2021-47086, CVE-2024-42153, CVE-2024-40959, CVE-2024-26777, CVE-2024-44944, CVE-2024-43856, CVE-2024-39301) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS linux-image-4.4.0-262-generic 4.4.0-262.296 Available with Ubuntu Pro linux-image-4.4.0-262-lowlatency 4.4.0-262.296 Available with Ubuntu Pro linux-image-generic 4.4.0.262.268 Available with Ubuntu Pro linux-image-generic-lts-xenial 4.4.0.262.268 Available with Ubuntu Pro linux-image-lowlatency 4.4.0.262.268 Available with Ubuntu Pro linux-image-lowlatency-lts-xenial 4.4.0.262.268 Available with Ubuntu Pro linux-image-virtual 4.4.0.262.268 Available with Ubuntu Pro linux-image-virtual-lts-xenial 4.4.0.262.268 Available with Ubuntu Pro Ubuntu 14.04 LTS linux-image-4.4.0-262-generic 4.4.0-262.296~14.04.1 Available with Ubuntu Pro linux-image-4.4.0-262-lowlatency 4.4.0-262.296~14.04.1 Available with Ubuntu Pro linux-image-generic-lts-xenial 4.4.0.262.296~14.04.1 Available with Ubuntu Pro linux-image-lowlatency-lts-xenial 4.4.0.262.296~14.04.1 Available with Ubuntu Pro linux-image-virtual-lts-xenial 4.4.0.262.296~14.04.1 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.
