========================================================================== Ubuntu Security Notice USN-7704-4 August 21, 2025
linux-nvidia 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-nvidia: Linux kernel for NVIDIA systems Details: 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: - Cryptographic API; - Arm Firmware Framework for ARMv8-A(FFA); - Multiple devices driver; - Media drivers; - Network drivers; - NVDIMM (Non-Volatile Memory Device) drivers; - NVME drivers; - x86 platform drivers; - TCM subsystem; - Virtio drivers; - File systems infrastructure; - SMB network file system; - LZO compression library; - Digital Audio (PCM) driver; - Tracing infrastructure; - Padata parallel execution mechanism; - CAN network layer; - Networking core; - TIPC protocol; - ALSA framework; (CVE-2025-38079, CVE-2025-38048, CVE-2025-38075, CVE-2025-38077, CVE-2025-38035, CVE-2025-38037, CVE-2025-38034, CVE-2025-38058, CVE-2025-38004, CVE-2025-38031, CVE-2025-38078, CVE-2025-38044, CVE-2025-38066, CVE-2025-38052, CVE-2025-38043, CVE-2025-38065, CVE-2025-38003, CVE-2025-38061, CVE-2025-38051, CVE-2025-38072, CVE-2025-38068) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 22.04 LTS linux-image-5.15.0-1085-nvidia 5.15.0-1085.86 linux-image-5.15.0-1085-nvidia-lowlatency 5.15.0-1085.86 linux-image-nvidia 5.15.0.1085.85 linux-image-nvidia-5.15 5.15.0.1085.85 linux-image-nvidia-lowlatency 5.15.0.1085.85 linux-image-nvidia-lowlatency-5.15 5.15.0.1085.85 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.
