CVE-2026-53670

PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, in the Prevail eBPF verifier, EbpfTransformer::add silently skips offset-variable updates when the destination register carries a non-singleton typeset two or more simultaneously possible...

CVE-2026-53706

PREVAIL is a Polynomial-Runtime eBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4 , the verifier accepts ALU32 ADD and SUB instructions that operate on pointer-typed registers without checking the is64 flag . Because ALU32 arithmetic zero-extends the 32-bit result, the ...

CVE-2026-53670 PREVAIL: Non-singleton typeset in add() skips offset update, allowing OOB access to pass eBPF verification

CVE-2026-53670

PREVAIL , a polynomial-runtime eBPF verifier using an abstract interpretation layer, is vulnerable to a verifier bypass prior to version 0.2.4 . In the EbpfTransformer::add() function, offset-variable updates are silently skipped when the destination register carries a non-singleton typeset (two ...

CVE-2026-53671

PREVAIL is a polynomial-runtime eBPF verifier. Prior to version 0.2.4 , its abstract transformer in do_mem_store (src/crab/ebpf_transformer.cpp) silently ignores writes through a T_CTX -typed base register, and the checker's T_CTX bounds arm never tests AccessType::write. An attacker can craft an...
