Low risk16th percentile - higher than 16% of all known CVEs
Summary
A vulnerability in Sony XAV-9500ES devices allows physically present attackers to execute arbitrary code in the context of the gpsd daemon. The flaw is due to improper validation of NMEA data length before copying to a fixed-length buffer, leading to a buffer overflow. Authentication is not required.
Risk Assessment
An attacker with physical access can execute arbitrary code on the device, potentially leading to full system compromise.
Recommendation
Restrict physical access and apply manufacturer updates. If possible, disable unnecessary services like gpsd.

Original NVD description (English source)
Sony XAV-9500ES gpsd Buffer Overflow Arbitrary Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Sony XAV-9500ES devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of NMEA data by the gpsd daemon. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the gpsd daemon. Was ZDI-CAN-29060.
