Ubuntu Security Notice
Ubuntu USN-8845-1 Fixes GVfs Vulnerabilities
Ubuntu GVfs updates fix malicious-SFTP data handling and a separate local ownership flaw with narrower release scope. Update installed backends and libraries, save work and restart user sessions; closing one file-manager window is not sufficient.
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.
