Update Summary
USN-8729-1 fixes several security issues in the Linux kernel for Ubuntu 24.04 LTS (noble). The update affects multiple kernel flavors and requires a reboot; due to an ABI change, third-party kernel modules must be recompiled and reinstalled.
Update Details
Security
- Several security issues were fixed in the Linux kernel, which could possibly allow an attacker to compromise the system.
- Affected areas include ARM32/ARM64, networking, filesystems, io_uring, memory management, Bluetooth, Netfilter, LSM, and multiple drivers.
Hints
- After updating, reboot the computer to apply all changes.
- Due to an unavoidable ABI change, third-party kernel modules must be recompiled and reinstalled.
