========================================================================== Ubuntu Security Notice USN-6867-1 July 03, 2024
linux-bluefield, linux-iot vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 20.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-bluefield: Linux kernel for NVIDIA BlueField platforms - linux-iot: Linux kernel for IoT platforms Details: It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service. (CVE-2024-0841) 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: - ARM32 architecture; - PowerPC architecture; - x86 architecture; - DMA engine subsystem; - EFI core; - GPU drivers; - InfiniBand drivers; - Multiple devices driver; - Network drivers; - Power supply drivers; - TCM subsystem; - Userspace I/O drivers; - USB subsystem; - Framebuffer layer; - AFS file system; - File systems infrastructure; - BTRFS file system; - Ext4 file system; - Bluetooth subsystem; - Networking core; - IPv4 networking; - IPv6 networking; - L2TP protocol; - MAC80211 subsystem; - Netfilter; - Netlink; - Wireless networking; (CVE-2021-47063, CVE-2024-26751, CVE-2024-26848, CVE-2024-26748, CVE-2024-26733, CVE-2024-26735, CVE-2024-26805, CVE-2024-26804, CVE-2024-26793, CVE-2023-52504, CVE-2024-27417, CVE-2024-27405, CVE-2024-26778, CVE-2024-27414, CVE-2024-26801, CVE-2024-26835, CVE-2024-27413, CVE-2024-26766, CVE-2024-27410, CVE-2024-27412, CVE-2024-26773, CVE-2024-26777, CVE-2024-26839, CVE-2024-26764, CVE-2024-26712, CVE-2024-26788, CVE-2024-26688, CVE-2024-26754, CVE-2021-47070, CVE-2024-26752, CVE-2024-26845, CVE-2024-26791, CVE-2024-26763, CVE-2024-27416, CVE-2024-26779, CVE-2024-26749, CVE-2024-26736, CVE-2024-26840, CVE-2024-26772, CVE-2024-26790) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.4.0-1038-iot 5.4.0-1038.39 linux-image-5.4.0-1086-bluefield 5.4.0-1086.93 linux-image-bluefield 5.4.0.1086.82 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.
