PoC Exploit Released for DirtyDecrypt Linux Kernel Vulnerability

A proof‑of‑concept exploit has been released for the DirtyDecrypt (DirtyCBC) Linux kernel vulnerability, which was discovered and reported by the Zellic and V12 security team on May 9, 2026. The flaw, a local privilege escalation bug, allows a non‑privileged user to read sensitive files and execute arbitrary commands as root on affected systems. Although the kernel maintainers had already patched the issue, the PoC demonstrates that the vulnerability can be leveraged to gain full root privileges.

The exploit is a duplicate of an earlier vulnerability that had been reported years ago, but the new PoC shows a more practical attack vector. The PoC code is publicly available, making it a serious threat for any unpatched system. Administrators should apply the latest kernel update that fixes DirtyDecrypt immediately to prevent exploitation.
