Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-8261-1 May 07, 2026 linux-xilinx vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-xilinx: Linux kernel for Xilinx systems Details: Josh Eads, Kristoffer Janke, Eduardo Vela Nava, Tavis Ormandy, and Matteo Rizzo discovered that some AMD Zen processors did not properly verify the signature of CPU microcode. This flaw is known as EntrySign. A privileged attacker could possibly use this issue to cause load malicious CPU microcode causing loss of integrity and confidentiality. (CVE-2024-36347) Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM). An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege escalation, or possibly escape a container. (LP: #2143853, CVE-2026-23268, CVE-2026-23269, CVE-2026-23403, CVE-2026-23404, CVE-2026-23405, CVE-2026-23406, CVE-2026-23407, CVE-2026-23408, CVE-2026-23409, CVE-2026-23410, CVE-2026-23411) Several security issues were discovered in the Linux kernel.

problem can be corrected by updating your system to thefollowing package versions: Ubuntu 24.04 LTS linux-image-6.8.0-1029-xilinx 6.8.0-1029.30 linux-image-xilinx 6.8.0.1029.30 linux-image-xilinx-6.8 6.8.0.1029.30 linux-image-xilinx-zynqmp 6.8.0.1029.30 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.

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.

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.

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-8152-1 April 06, 2026 linux-oem-6.17 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-oem-6.17: Linux kernel for OEM systems Details: It was discovered that some AMD Zen 5 processors supporting RDSEED instruction did not properly handle entropy, potentially resulting in the consumption of insufficiently random values. A local attacker could possibly use this issue to influence the values returned by the RDSEED instruction causing loss of confidentiality and integrity. (CVE-2025-62626) Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM). An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege escalation, or possibly escape a container. (LP: #2143853, CVE-2026-23268, CVE-2026-23269, CVE-2026-23403, CVE-2026-23404, CVE-2026-23405, CVE-2026-23406, CVE-2026-23407, CVE-2026-23408, CVE-2026-23409, CVE-2026-23410, CVE-2026-23411) Several security issues were discovered in the Linux kernel.

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.
