Ubuntu USN-8903-1 Linux kernel multiple vulnerabilities advisory

USN-8903-1: Linux kernel vulnerabilities Overview Published Date: October 8, 2026 Summary: Multiple security issues were discovered in the Linux kernel. An attacker could exploit these issues to compromise the system. Affected Versions: 24.04 LTS, 22.04 LTS Scope Affected Subsystems: - ARM32 architecture - ARM64 architecture - MIPS architecture - x86 architecture - Intel NPU driver - Auxiliary display driver - ZRAM block device driver - GPIO subsystem - CPU driver - HID subsystem - I2C subsystem - IIO subsystem - InfiniBand driver - Input device core driver - Input device (mouse) driver - Multifunction device driver - Media driver - Fasttcp driver - Ethernet bonding driver - Network driver - Mellanox network driver - Microsoft Azure network adapter (MANA) driver - Texas Instruments network driver - NVMEM (non-volatile memory) driver - Parport driver Remediation Update Notes: - A system restart is required after a standard system update to apply all changes. - Due to unavoidable ABI changes, the kernel update has been assigned a new version number, requiring all third-party kernel modules to be recompiled and reinstalled. - Standard system upgrades will perform this automatically unless the standard kernel meta-packages (such as linux-generic, linux-generic-lts-release, linux-virtual, linux-powerpc) are manually uninstalled.
