PoC Released for DirtyDecrypt Linux Kernel Vulnerability

Proof-of-concept exploit code has been released for DirtyDecrypt, a Linux kernel vulnerability that allows attackers to escalate privileges to root level access. The flaw affects distributions like Arch Linux, Fedora, and openSUSE that have the RxGK security component enabled, and it stems from a missing copy-on-write guard that lets attackers write data to privileged system files. This vulnerability is the latest in a series of similar Linux kernel bugs including CopyFail, DirtyFrag, and Fragnesia, all capable of granting root access on vulnerable systems.
