Encryption key disclosure via unwiped freed memory
Published Jul 21, 2026 · Updated Jul 21, 2026
Sensitive-information exposure in kronosnet 1.34 and earlier allows local users to recover encryption keys from freed memory. Cryptographic configuration teardown frees key-bearing memory without first wiping it, leaving raw keys recoverable through a separate memory-disclosure technique. Low-privileged local access and a separate ability to disclose process memory are required; recovered keys expose cluster traffic and enable packet injection or service interruption.
