security advisorydenial of serviceubuntuUbuntu 23.10: USN-6873-1 Critical: Linux Kernel Issues Resolved
Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-6873-1 July 04, 2024 linux-aws, linux-aws-6.5, linux-oem-6.5, linux-oracle, linux-oracle-6.5, linux-starfive vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 23.10 - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-oracle: Linux kernel for Oracle Cloud systems - linux-starfive: Linux kernel for StarFive processors - linux-aws-6.5: Linux kernel for Amazon Web Services (AWS) systems - linux-oem-6.5: Linux kernel for OEM systems - linux-oracle-6.5: Linux kernel for Oracle Cloud systems Details: It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. (CVE-2024-21823) 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 subsystem: - Netfilter; (CVE-2024-26643, CVE-2024-26925, CVE-2024-26924, CVE-2024-26809) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 23.10 linux-image-6.5.0-1016-starfive 6.5.0-1016.17 linux-image-6.5.0-1022-aws 6.5.0-1022.22 linux-image-6.5.0-1025-oracle 6.5.0-1025.25 linux-image-6.5.0-1025-oracle-64k 6.5.0-1025.25 linux-image-aws 6.5.0.1022.22 linux-image-oracle 6.5.0.1025.27 linux-image-oracle-64k 6.5.0.1025.27 linux-image-starfive 6.5.0.1016.18 Ubuntu 22.04 LTS linux-image-6.5.0-1022-aws 6.5.0-1022.22~22.04.1 linux-image-6.5.0-1025-oem 6.5.0-1025.26 linux-image-6.5.0-1025-oracle 6.5.0-1025.25~22.04.1 linux-image-6.5.0-1025-oracle-64k 6.5.0-1025.25~22.04.1 linux-image-aws 6.5.0.1022.22~22.04.1 linux-image-oem-22.04 6.5.0.1025.27 linux-image-oem-22.04a 6.5.0.1025.27 linux-image-oem-22.04b 6.5.0.1025.27 linux-image-oem-22.04c 6.5.0.1025.27 linux-image-oem-22.04d 6.5.0.1025.27 linux-image-oracle 6.5.0.1025.25~22.04.1 linux-image-oracle-64k 6.5.0.1025.25~22.04.1 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.

Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-6651-3 February 29, 2024 linux-starfive-6.5 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-starfive-6.5: Linux kernel for StarFive processors Details: It was discovered that a race condition existed in the ATM (Asynchronous Transfer Mode) subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-51780) It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-51781) Zhenghan Wang discovered that the generic ID allocator implementation in the Linux kernel did not properly check for null bitmap when releasing IDs. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-6915) Robert Morris discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain server commands fields, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-0565) Jann Horn discovered that the io_uring subsystem in the Linux kernel did not properly handle the release of certain buffer rings. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-0582) Jann Horn discovered that the TLS subsystem inthe Linux kernel did not properly handle spliced messages, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-0646) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS: linux-image-6.5.0-1008-starfive 6.5.0-1008.9~22.04.1 linux-image-starfive 6.5.0.1008.9~22.04.3 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.
