CVE-2021-37848

Name of the Vulnerable Software and Affected Versions: Pengutronix barebox versions through 2021.07.0

Description: The issue is related to the common/password.c file in Pengutronix barebox, where the use of strncmp during hash comparison leaks timing information. This could potentially be exploited to gain unauthorized access.

Recommendations: For versions through 2021.07.0, consider updating to a version later than 2021.07.0 to resolve the issue. As a temporary workaround, consider restricting access to the common/password.c file or the affected hash comparison function until a patch is available.
