Update Summary
USN-8726-1 fixes multiple Linux kernel security issues in Ubuntu Server 24.04 LTS. It includes a privilege-escalation fix for CVE-2025-10263 and updates the kernel ABI, requiring third-party kernel modules to be recompiled.
Update Details
Security
- Fixed a privilege-escalation issue on some Arm processors where a broadcast TLB invalidation could complete before memory writes were globally observed, potentially bypassing memory protections. (CVE-2025-10263)
- Addressed multiple Linux kernel security issues across many subsystems that could allow an attacker to compromise the system.
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.
- Standard system upgrades should handle the ABI transition automatically unless standard kernel metapackages were manually removed.
