Overview
In June 2026, two critical Linux kernel vulnerabilities were publicly disclosed, each enabling local privilege escalation to root. DirtyClone, a variant of the DirtyFrag vulnerability class, allows attackers to corrupt file-backed memory via cloned network packets. The pedit COW flaw involves an out-of-bounds write in the packet-editing subsystem that poisons shared page-cache memory. Both vulnerabilities have working public exploits, underscoring the need for immediate patching to prevent system compromise.
