Summary

CVE-2026-49317 is a low-severity Failing Open (CWE-636) vulnerability in Mitre (inferred from references). Its CVSS base score is 1.0 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Service Stop (T1489); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to CP-12 (Safe Mode) and SA-11 (Developer Testing and Evaluation) — see the control section below for these in your framework.

Vulnerability Data

Incorrect behavior order in the Infotainment / Digital Round display of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker to bypass the PIN entry screen. The Infotainment uses presence of Wireless Control Module (WCM)…

more

traffic during its boot window as a proxy for whether an immobilizer is fitted; if no WCM messages are observed, it skips the PIN entry screen and shows the normal user interface. An attacker who silences the WCM during the boot window — for example via a separately tracked CAN bus-off technique — can present a fully unlocked Infotainment despite the PIN never being entered. Specific timing and protocol details have been withheld pending vendor remediation.

Mitigating Controls (NIST 800-53 r5) AI

SC-24 directly requires the system to fail to a known state that preserves security properties, structurally stopping fallback to a less-secure mode.

SI-17 mandates explicit fail-safe procedures that activate on indicated failures, preventing the insecure fallback behavior.

CP-12 forces entry into a safe mode on detected conditions, limiting exposure but not covering every failure path.

Developer testing and evaluation at post-design stages can discover incorrect ordering of related behaviors before deployment.

Input validation directly requires checking for unexpected or malformed conditions before they propagate.

Vulnerability scanning may surface order-related weaknesses after code is built but does not address their root cause.
