DirtyDecrypt: Public PoC Released for Linux Kernel Root Escalation Flaw

A public proof-of-concept exploit is now available for DirtyDecrypt, a recently patched local privilege escalation vulnerability in the Linux kernel’s rxgk module. The flaw allows an attacker with local access to gain root on affected Linux systems.

Container environments and multi-tenant Linux hosts are particularly at risk since local access is commonly available to unprivileged workloads. Confirm your kernel version against vendor security advisories and patch promptly; the existence of a public PoC means exploitation should be considered likely on unpatched systems.
