ZDI-26-475: (Pwn2Own) Sony XAV-9500ES AVRCP_Br_Response_Parser Heap-based Buffer Overflow Remote Code Execution Vulnerability
Sony XAV-9500ES AVRCP_Br_Response_Parser Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Sony XAV-9500ES devices. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability. The specific flaw exists within the handling of AVRCP packets. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-28995.
AI Analysis
Technical Summary
The Sony XAV-9500ES device contains a heap-based buffer overflow vulnerability in the handling of AVRCP packets due to improper validation of user-supplied data length before copying to a heap buffer. Exploitation requires an attacker to pair a malicious Bluetooth device with the target system, enabling remote code execution in the device's context. The vulnerability is tracked as CVE-2026-18282 and was publicly disclosed by the Zero Day Initiative on July 29, 2026. Sony has issued a software update to remediate this vulnerability.
Potential Impact
Successful exploitation allows remote code execution with high impact on confidentiality, integrity, and availability of the affected device. An attacker can execute arbitrary code remotely after pairing a malicious Bluetooth device, potentially compromising the device fully.
Mitigation Recommendations
Sony has released an official software update to fix this vulnerability. Users of Sony XAV-9500ES devices should apply the update available at Sony's support site to mitigate the risk. No additional mitigation steps are indicated by the vendor advisory.
