**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue occurs in the `btf name valid section()` function when the length of the name string is 1 and the value of `name[0]` is a NULL byte, causing an out-of-bounds vulnerability. The return value is true, allowing the invalid name to pass the check. To resolve this, it is necessary to check if the first position is a NULL byte and if the first character is printable. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
