**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to an overflow in the `get free elt()` function, specifically with `tracing map->next elt`, which can lead to an infinite loop and a CPU hang problem when trying to insert an element into a full `tracing map` using ` tracing map insert()`. This occurs because once `tracing map->next elt` overflows, new elements can still be inserted into the `tracing map`, even though the maximum number of elements (`max elts`) has been reached. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
