DirtyClone: New Linux Kernel LPE Lets Local Users Escalate to Root
JFrog Security Research disclosed DirtyClone (CVE‑2026‑43503), a high‑severity Linux kernel LPE that lets any unprivileged user corrupt file‑backed memory via a cloned network packet and gain root without leaving logs. The flaw survives earlier DirtyFrag fixes and impacts Debian, Ubuntu, Fedora and other modern distributions. Patch kernels to v7.1‑rc5 or apply backports immediately.
