CVE-2026-74636

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

Description A race condition exists between the event define fields() and update event fields() functions. This occurs when one CPU loads a module and executes event define fields() while another CPU executes trace event update all(), which calls update event fields(). The issue stems from the fact that access to class->fields is not protected by the event mutex within the trace event update all() function, potentially leading to a kernel panic.

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