DirtyClone — CVE-2026-43503
A Linux kernel local privilege escalation and page-cache write. DirtyClone is the fourth public member of the DirtyPipe / DirtyFrag family: it forces the kernel to run an in-place ESP (IPsec) decrypt over a file-backed page-cache page the attacker only has read access to, mutating that page in RAM. With the AES-CBC key/IV chosen so the decrypt writes attacker-controlled bytes,
/usr/bin/su is rewritten with a tiny setuid(0)+execve("/bin/sh") ELF and invoking it yields root.

+1🔑 Onelogon: Taking over Active Directory Accounts via Netlogon
We analyzed Netlogon, bypassed the Zerologon patch, resulting in a full auth bypass. An attacker can leverage this to compromise computer accounts, or even the entire AD. Non-standard config must be present tho
