Threat Score
Dirty Frag is a set of Linux kernel privilege-escalation bugs (CVE-2026-43284 and CVE-2026-43500) that misuse page-cache and sk_buff frag handling to enable attackers to corrupt read-only pages in memory and escalate to root; the issues affect IPsec ESP and RxRPC code paths, can be chained for reliable local root on major distributions, and should be mitigated immediately by applying vendor patches and recommended hardening.
