CVE-2022-21658

A race condition flaw was found in Rust's std::fs::remove_dir_all function. Rust applications that use this function may be vulnerable to a race condition where an unprivileged attacker can trick the application into deleting files and directories, causing an impact on system data integrity. If the application is privileged, an attacker can possibly delete files they would not usually have access to.

This flaw has been given a Severity of Moderate because it is not exploitable at will on every Rust program as it requires a specific scenario where a privileged program uses a specific Rust stdlib function, the attacker has some knowledge of the program's file operations, and has the normal limitations and challenges of a Time-of-check to time-of-use (TOCTOU). It must also be carried out by an unprivileged attacker.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
