CVE-2026-42772

A flaw in OpenSSL allows a remote attacker to cause a Denial of Service (DoS) by exploiting an inefficient QUIC stream reassembly algorithm. When packets arrive out of order, the software falls back to a head-to-tail linear search for fragments in a doubly-linked list. By manipulating sequence of...
