Ubuntu USN-8816-3 Fixes Linux kernel (Oracle) Vulnerabilities
Ubuntu 24.04 Oracle-cloud 7.0 kernel updates require matching standard or 64k binaries and a reboot. Update reusable launch images, check external modules and verify the running kernel; this is not an Oracle Linux update.
Ubuntu USN-8818-3 Updates Cloud and IoT Kernels for 20 Vulnerabilities
Ubuntu 20.04 Pro updates cover AWS, Azure, Azure FDE and Intel IoTG 5.15 kernels. Preserve the installed flavor, prepare encrypted-boot or device recovery as appropriate, and complete module checks and the required reboot.
Ubuntu USN-8819-3 Updates Azure and AWS Kernels for Three Vulnerabilities
Older Ubuntu Azure and AWS-HWE kernels require release-specific Pro or Legacy Support access. Match image and metapackage versions separately, verify recovery and module readiness, then reboot; a targeted fix does not establish broad application support.
Ubuntu USN-8842-1 Updates NVIDIA Kernels for 18 Vulnerabilities
Ubuntu NVIDIA kernel updates cover standard, low-latency and page-size variants on specified releases. Install the matching kernel and reboot after module checks; this is not a standalone graphics-driver or CUDA compatibility update.
Ubuntu USN-8728-3 Updates the Oracle Kernel for 1,417 Vulnerabilities
Ubuntu 24.04 Oracle-cloud 7.0 kernel updates include two KEV-listed vulnerabilities. Match the Oracle variant, update and reboot, and assess suspicious activity separately; the large CVE count does not establish every issue is reachable on one instance.
Ubuntu USN-8816-2 Updates GCP and OEM Kernels for 101 Vulnerabilities
Ubuntu's GCP and OEM kernel updates cover distinct release, flavor and page-size combinations. Install the matching binaries, verify external modules and reboot with recovery access; switching flavors is a separate change, not a compatibility shortcut.
Ubuntu USN-8729-6 Updates AWS Kernels for 97 Vulnerabilities
Ubuntu 22.04 and 24.04 AWS 6.8 kernel updates require matching image/metapackage variants, module readiness and a reboot. Update launch templates too; restarting an application or replacing a container does not change the host's running kernel.
Ubuntu USN-8487-2 Corrects the curl CVE-2026-8927 Fix
Ubuntu 14.04 Legacy Support corrects an incomplete curl fix involving retained proxy-authentication credentials. Update installed libcurl consumers as well as the command-line tool; the earlier advisory's package alone does not establish protection.
Ubuntu USN-8839-1 Fixes Atril Vulnerabilities
Ubuntu Atril updates address code-execution risk in crafted PDF actions, with two older flaws scoped only to Ubuntu 16.04. Install the release-matched viewer update and reopen sessions before handling unknown documents.
Ubuntu USN-8838-1 Fixes catdoc Vulnerabilities
Ubuntu catdoc updates fix malformed Office-document parsing that can crash extraction jobs or permit code execution. Update the binary used by automated upload processing as well as desktop tools, and validate ordinary document and spreadsheet extraction.
