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.
