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 prevail eBPF 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...

CVE-2026-53706 PREVAIL: ALU32 pointer arithmetic accepted without is64 gate — verifier emits false PASS for pointer-corrupting programs

PREVAIL is a Polynomial-Runtime EBPF Verifier using an Abstract Interpretation Layer. Prior to version 0.2.4, the prevail eBPF 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...

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...
