FAQ

According to the CVSS metric, the attack vector is physical (AV:P). What does that mean for this vulnerability? A physical attack vector means the attacker must have direct physical access to the device in order to exploit the vulnerability. In this case, the issue can only be triggered by physically connecting or manipulating hardware that interacts with the affected system. Remote or network‑based attacks are not possible for this vulnerability.
