    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...

    Azure ND GB300 v6 Delivers 1.1M Tokens/sec Inference

    Microsoft’s new ND GB300 v6 virtual machines have cracked a milestone that changes the practical limits of public‑cloud AI inference: one NVL72 rack of Blackwell Ultra GPUs sustained an aggregated throughput of roughly 1.1 million tokens per second, a result validated by an independent benchmark...
