CVE-2025-68186

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

Description The ring buffer map get reader() function exhibited overly strict behavior, triggering a warning when the reader caught up to the writer in certain scenarios. Specifically, when the reader caught up to the writer and data remained on the reader page, rb get reader page() could return NULL, incorrectly triggering a warning. This occurred because the code did not account for this acceptable situation. The issue was related to the handling of reader pages within the ring buffer mechanism.

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