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.
