CVE-2026-73829 Non-atomic hash-credential dedup in mpp Tempo allows replay of a confirmed payment under a concurrent race

Time-of-check Time-of-use TOCTOU Race Condition in ZenHive mpp allows an unauthenticated remote client to redeem one confirmed on-chain payment for multiple paid-resource accesses. The type="hash" credential path in MPP.Methods.Tempo.verify/2 guards against replay with a non-atomic check-then-mar...

CVE-2026-73829

ZenHive mpp (Elixir MPP library) versions 0.2.0 through 0.6.0 contain a TOCTOU race condition in the type="hash" credential path of MPP.Methods.Tempo.verify/2. The dedup check-then-mark sequence is non-atomic: check_hash_unused/2 reads the store, an on-chain receipt is verified, and only then doe...

CVE-2024-13942

Secure BootROM of RK3588s SoC is vulnerable to a time-of-check to time-of-use attack in case of booting from external media SPI NOR or NAND, EMMC or SD. The code reads the header of the next-stage loader twice. The header contains hashes of the executable modules and is signed with a private key,...

CVE-2024-13942

The RK3588s BootROM (secure) version 350B20210512V100 reads the next-stage loader header twice: a partial read (module hashes only) and a full read (with signature). Module authenticity is checked against the partial data, enabling a TOCTOU attack where an attacker swaps in a modified header on-t...
