CVE-2021-22552 (GCVE-0-2021-22552)

Vulnerability from cvelistv5 – Published: 2021-08-02 15:40 – Updated: 2024-09-17 01:40

Title

Memory overread secure enclave in Asylo 0.6.2

Summary

An untrusted memory read vulnerability in Asylo versions up to 0.6.1 allows an untrusted attacker to pass a syscall number in MessageReader that is then used by sysno() and can bypass validation. This can allow the attacker to read memory from within the secure enclave. We recommend updating to Asylo 0.6.3 or past https://github.com/google/asylo/commit/90d7619e9dd99bcdb6cd28c7649d741d254d9a1a

Severity
