Security researchers have published a detailed, working exploit for a Linux kernel use-after-free that lets an unprivileged local user escalate to root and break out of a container.
The flaw, CVE-2026-23111, sits in the kernel's nf_tables packet-filtering code and was patched upstream on February 5, 2026.
Exodus Intelligence released its full technical walkthrough on June 8, and it is not even the first public exploit: FuzzingLabs published an independent reproduction back in April.
