CVE-2022-25328 (GCVE-0-2022-25328)

Vulnerability from cvelistv5 – Published: 2022-02-25 11:00 – Updated: 2025-04-21 13:56

Summary

The bash_completion script for fscrypt allows injection of commands via crafted mountpoint paths, allowing privilege escalation under a specific set of circumstances. A local user who has control over mountpoint paths could potentially escalate their privileges if they create a malicious mountpoint path and if the system administrator happens to be using the fscrypt bash completion script to complete mountpoint paths. We recommend upgrading to version 0.3.3 or above

Severity ?
