Tag: DirtyClone Linux Kernel Flaw

Within the DirtyFrag family, DirtyClone is a new Linux kernel privilege escalation. On June 25, JFrog Security Research released the first public demonstration of this variant, a working exploit walkthrough. It is known as CVE-2026-43503 (CVSS 8.8) and allows a local user to get root by using a cloned network packet to damage file-backed memory. Update your kernel right away if it doesn't already contain the fix, which was added to the mainline on May 21.
