    CVE-2026-1979: mruby VM Use-After-Free from faulty JMPNOT optimization

    A recently assigned CVE, CVE‑2026‑1979, exposes a use‑after‑free (UAF) in mruby’s virtual machine caused by an over‑aggressive bytecode optimization that converts JMPNOT instructions into JMPIF instructions — a logic error that corrupts compiled bytecode and can lead to memory corruption when...
