CVE-2026-118605: Alpine iLX-F511 stack-based buffer overflow in prh_sdp_service_search_decode

CVE-2026-118605 · Severity: high · CVSS 8 · Published 2026-10-28

Alpine iLX-F511 is an in-vehicle infotainment system used in Alpine car audio equipment. A stack-based buffer overflow in the Bluetooth service search function allows a nearby attacker to execute arbitrary code with root privileges on the device by pairing a malicious Bluetooth device and sending specially crafted data. This could result in complete compromise of the vehicle's entertainment and control systems.

Technologies: Alpine iLX-F511. Vendors: Alpine.

Technical details

A stack-based buffer overflow exists in the prh_sdp_service_search_decode function due to insufficient validation of user-supplied data length before copying to a stack buffer. An attacker with the ability to pair a Bluetooth device (adjacent network access) can trigger the overflow to execute arbitrary code in the root context. A public advisory exists but no vendor fix is documented.
