Linux kernel local root escalation flaws multiple vulnerabilities memory corruption flaw (CVE-2026-80844)
Vulnerability
Summary
Hide ▲
Show ▼
Linux kernel local-privilege-escalation flaws across DirtyAH6, TUNderflow, PPPoEject, and DiagSpill now have public exploit code, leaving older systems exposed to local root risk until they are updated. Kernel maintainers have already fixed the issues, and up-to-date kernels are not affected. No real-world abuse has been reported yet, but public code increases the danger on shared systems.
