**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A use-after-free bug in the Linux kernel has been identified. The issue arises from the `cleanup srcu struct()` function not checking for a grace period that has not yet started but might start at any time. This could result in a use-after-free bug. The commit adds a check for a grace period that is needed but not yet started to `cleanup srcu struct()`. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
