No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The Remote Keyless Entry (RKE) receiving unit on certain Nissan, Kia, and Hyundai vehicles through 2017 allows remote attackers to perform unlock operations and force a resynchronization after capturing two consecutive valid key fob signals over the radio, aka a RollBack attack. The attacker retains the ability to unlock indefinitely.

Exploitation public PoC (EG-KEV: elevated) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
