PatchTheCVECVE-2026-75625: Kraken agents fail to verify peer-to-peer downloaded blobs against their requested SHA-256 digest before commi
CVE-2026-75625 is a critical-severity flaw (CVSS 9.0) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Kraken agents fail to verify peer-to-peer downloaded blobs against their requested SHA-256 digest before committing to the content-addressable cache, relying only on CRC32 checksums for piece validation. Attackers on the agent-to-agent path or malicious peers can supply substituted content with forged CRC32 corrections that passes per-piece checks, poisoning the cache with attacker-chosen container image layers or manifests that are re-seeded and
