LowCVSS 2.4Exploitation Probability (EPSS)
Low risk24th percentile - higher than 24% of all known CVEs
Summary
A vulnerability in Sony XAV-9500ES devices allows physically present attackers to bypass authorization by connecting a crafted USB device. The flaw exists in the udev rules, which can trigger instantiation of restricted USB device types. Authentication is not required to exploit this vulnerability.
Risk Assessment
An attacker with physical access can bypass authorization mechanisms, potentially leading to unauthorized access to system functions.
Recommendation
Restrict physical access to the device and monitor connected USB devices. Follow manufacturer updates and apply patches if available.

- CVE-2026-18278Low
A vulnerability in Sony XAV-9500ES devices allows network-adjacent attackers to disclose sensitive information via an out-of-bounds read when handling Bluetooth L2CAP packets. The attacker must first pair a malicious Bluetooth device with the target system.
Original NVD description (English source)
Sony XAV-9500ES udev USB Rules Authorization Bypass Vulnerability. This vulnerability allows physically present attackers to bypass authorization on affected installations on Sony XAV-9500ES devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the udev rules. A crafted USB device connected to the system can trigger instantiation of otherwise restricted USB device types. An attacker can leverage this vulnerability to bypass authorization on the system. Was ZDI-CAN-28992.
