Update Summary

USN-8728-1 updates the Ubuntu 24.04 LTS GCP kernel to address multiple security issues, including CVE-2025-10263 and CVE-2025-54518. The update also includes an ABI change that requires third-party kernel modules to be recompiled and reinstalled.

Update Details

Security

  • Fixes an Arm TLB invalidation issue that could allow memory writes after permissions were revoked, bypassing memory protections or escalating privileges (CVE-2025-10263).
  • Fixes an AMD Zen 2 operation cache isolation issue that could allow instruction corruption at higher privilege levels, resulting in privilege escalation (CVE-2025-54518).
  • Addresses multiple additional Linux kernel security issues across architecture, driver, filesystem, networking, and security subsystems.

Hints

  • After updating, reboot the system to apply the kernel changes.
  • Due to an unavoidable ABI change, third-party kernel modules must be recompiled and reinstalled.
  • A standard system upgrade will handle the module rebuild if the standard kernel metapackages are installed.
