DirtyDecrypt: PoC Released for yet another Linux flaw
DirtyDecrypt (CVE-2026-31635): working PoC out for a Linux kernel LPE flaw. Missing COW guard in rxgk_decrypt_skb lets local attackers reach root. After Copy Fail, Dirty Frag, and Fragnesia, here comes DirtyDecrypt, another local privilege escalation vulnerability in the kernel, this time with a working proof-of-concept already out in the open.

After Copy Fail, Dirty Frag, and Fragnesia, here comes DirtyDecrypt, another local privilege escalation vulnerability in the kernel, this time with a working proof-of-concept already out in the open.
The flaw was discovered and reported on May 9, 2026 by the Zellic and V12 security team, who kernel maintainers then told that it was a duplicate of something already fixed upstream. No CVE was assigned directly to their report, but the National Vulnerability Database includes a link to the DirtyDecrypt PoC in the record for CVE-2026-31635 (CVSS 7.5), making the connection clear enough. The exploit code is publicly available on GitHub.
