**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 `netlbl calipso add pass()` function when IPv6 support is disabled at boot. This occurs because the `calipso init()` function is not called, and as a result, the `netlbl calipso ops get()` function always returns NULL. The `netlbl calipso add pass()` function then allocates memory for the `doi def` variable but fails to free it with `calipso doi free()`, leading to a memory leak. The vulnerability was found by InfoTeCS on behalf of Linux Verification Center with Syzkaller. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
