AZL-105861 CVE-2026-77696 affecting package rust 1.96.1-2

Issue summary: SM2 signature generation uses non-constant-time arithmetic on secret values, forming a timing side-channel. Impact summary: An attacker able to measure SM2 signing times may learn information about the per-signature secret nonce, which over many signatures can, via a lattice / Hidd...

Gossipsub PRUNE.backoff Duration Overflow

Summary The Rust libp2p Gossipsub implementation accepts attacker-controlled PRUNE backoff values and may perform unchecked time arithmetic when storing backoff state. A specially crafted PRUNE control message with an extremely large backoff e.g. u64::MAX can lead to Duration/Instant overflow...
