Prior to version 0.2.4, the abstract transformer in prevail treats writes through a T_CTX-typed base register as a silent no-op: do_mem_store in src/crab/ebpf_transformer.cpp only models T_STACK stores, and the checker&#39;s T_CTX bounds arm never tests AccessType::write. An attacker can craft an eBPF program that overwrites a context field (e.g., ctx-&gt;data), reload that field typed as T_PACKET, and dereference an attacker-controlled address — and prevail will report the program as safe. This issue has been patched in version 0.2.4.</p> <p><strong>Affected:</strong> vbpf prevail</p> <p>PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer.
