**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a memory leak in the `perf env insert btf()` function when a duplicate BTF id is encountered. This function does not insert the duplicate id and causes a memory leak. The function has been modified to return a success or error value and free the memory if the insertion did not happen. Additionally, a return value of -1 has been added when an insertion error occurs in `perf env fetch btf()`. This vulnerability may allow an attacker to cause a denial of service. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
