CVE-2025-21898

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A potential division by zero issue has been resolved in the Linux kernel, specifically in the ftrace function function stat show(). The fix checks whether the denominator expression x * (x - 1) * 1000 mod {2^32, 2^64} produces zero and skips stddev computation in that case. The issue is related to avoiding potential division by zero errors.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
