security advisorykernel patchUbuntuUbuntu 20.04 LTS Linux Kernel Important Privilege Escalation Fix USN-8439-1
Several security issues were fixed in the Linux kernel.. ========================================================================== Ubuntu Security Notice USN-8439-1 June 16, 2026 linux-oracle-5.15 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-oracle-5.15: Linux kernel for Oracle Cloud systems Details: Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-2640) Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-32629) 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: - Network drivers; - NVME drivers; - SMB network file system; - Netfilter; - io_uring subsystem; (CVE-2024-35862, CVE-2024-50060, CVE-2026-23112, CVE-2026-23273, CVE-2026-23274, CVE-2026-23351) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS linux-image-5.15.0-1104-oracle 5.15.0-1104.110~20.04.1 Available with Ubuntu Pro linux-image-oracle 5.15.0.1104.110~20.04.1 Available with Ubuntu Pro linux-image-oracle-5.15 5.15.0.1104.110~20.04.1 Available with Ubuntu Pro After a standard system update you need to reboot your computer to make all the necessarychanges. 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.

An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - Cryptographic API; - UDF file system; - NFC subsystem; - Network traffic control; (CVE-2024-46777, CVE-2025-21735, CVE-2025-37849, CVE-2026-23060, CVE-2026-23074) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS linux-image-4.15.0-1152-oracle 4.15.0-1152.163 Available with Ubuntu Pro linux-image-4.15.0-1172-kvm 4.15.0-1172.177 Available with Ubuntu Pro linux-image-4.15.0-1190-aws 4.15.0-1190.203 Available with Ubuntu Pro linux-image-4.15.0-248-generic 4.15.0-248.260 Available with Ubuntu Pro linux-image-4.15.0-248-lowlatency 4.15.0-248.260 Available with Ubuntu Pro linux-image-aws-4.15 4.15.0.1190.188 Available with Ubuntu Pro linux-image-aws-lts-18.04 4.15.0.1190.188 Available with Ubuntu Pro linux-image-generic 4.15.0.248.232 Available with Ubuntu Pro linux-image-kvm 4.15.0.1172.163 Available with Ubuntu Pro linux-image-lowlatency 4.15.0.248.232 Available with Ubuntu Pro linux-image-oracle-4.15 4.15.0.1152.157 Available with Ubuntu Pro linux-image-oracle-lts-18.04 4.15.0.1152.157 Available with Ubuntu Pro linux-image-virtual 4.15.0.248.232 Available with Ubuntu Pro Ubuntu 16.04 LTS linux-image-4.15.0-1190-aws 4.15.0-1190.203~16.04.1 Available with Ubuntu Pro linux-image-aws-hwe 4.15.0.1190.203~16.04.1 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.
