Ubuntu Linux Kernel Security Fixes (USN-8905-2) for Multiple CVEs

Vulnerability Overview Vulnerability ID: USN-8905-2 Publication Date: 9 October 2026 Description: Multiple security issues were discovered in the Linux kernel, which an attacker could exploit to compromise the system. Affected Systems Affected System: Linux kernel (GCP) Affected Subsystems: - ARM32 architecture - ARM64 architecture - MIPS architecture - x86 architecture - Intel NPU Driver - Auxiliary display drivers - Compressed RAM block device driver - GPIO subsystem - GPU drivers - HID subsystem - I2C subsystem - IIO subsystem - InfiniBand drivers - Input Device core drivers - Input Device (Mouse) drivers - Multiple devices driver - Media drivers - Fstpc Driver - Ethernet bonding driver - Network drivers - Mellanox network drivers - Microsoft Azure Network Adapter (MANA) driver - Texas Instruments network drivers - NVMEM (Non Volatile Memory) drivers - Parport... Remediation Update Instructions: After standard system updates, a computer restart is required to apply all necessary changes. Note: Due to unavoidable ABI changes, the kernel update has been assigned a new version number, requiring the recompilation and reinstallation of all third-party kernel modules. This operation will be performed automatically during standard system upgrades, unless the standard kernel meta-packages (e.g., linux-generic, linux-generic-lts, linux-virtual, linux-powerpc) are manually uninstalled. Fixed Versions: - Ubuntu Release: 24.04 LTS noble - Package Versions: - linux-image-6.8.0-1070-gcp - 6.8.0-1070.78 - linux-image-6.8.0-1070-gcp-64k - 6.8.0-1070.78 - linux-image-gcp-6.8 - 6.8.0-1070.78 - linux-image-gcp-64k-6.8 - 6.8.0-1070.78 - linux-image-gcp-64k-lts-24.04 - 6.8.0-1070.78 - linux-image-gcp-lts-24.04 - 6.8.0-1070.78 References CVE IDs: - CVE-2026-92502 - CVE-2026-72046 - CVE-2026-64528 - CVE-2026-64527 - CVE-2026-64525 - CVE-2026-64524 - CVE-2026-64243 - CVE-2026-64242 - CVE-2026-64240 - CVE-2026-64239 Related Advisories USN IDs: - USN-8906-1 - USN-8905-1 - USN-8904-1 - USN-8903-1 - USN-8903-2 - USN-8889-1 - USN-8888-1 - USN-8888-2 - USN-8887-1 - USN-8887-2 Additional Information Reducing Security Risks: Ubuntu Pro provides ten years of security coverage for packages in more than 25,000 main and universe repositories, and is free for up to five machines. Code Blocks No POC code or exploit code is included in the page.
