CVE-2025-41259: CWE-367 Time-of-check time-of-use (TOCTOU) race condition in sbabic SWUpdate
SWUpdate before 2026.05 is affected by a time-of-check time-of-use (TOCTOU) race condition that allows local unprivileged attackers to escalate privileges to root or install untrusted contents using a signed update.
AI Analysis
Technical Summary
SWUpdate versions prior to 2026.05 contain a TOCTOU race condition (CWE-367) that can be exploited locally by unprivileged users to gain root privileges or install unauthorized content despite the use of signed updates. The vulnerability arises from a timing issue between the check and use of resources during the update process. The CVSS 4.0 score is 7.3, indicating high severity. No official remediation or patch has been disclosed by the vendor at this time.
Potential Impact
Successful exploitation allows local unprivileged attackers to escalate their privileges to root or install untrusted content on the affected system. This compromises system integrity and security by bypassing update verification mechanisms.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local access to trusted users only and monitor for any suspicious activity related to the update process.
