CVE-2026-72012

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

Description An issue exists in the tracing/osnoise component where the synchronize rcu() function is not called during unregistration. This failure to synchronize allows the reference on the tracer to be released before RCU readers traversing the instance list have finished their operations. RCU (Read-Copy-Update) is a synchronization mechanism that allows multiple readers to access data simultaneously while it is being updated.

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