ZDI-26-475: (Pwn2Own) 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 ZDI has assigned a CVSS rating of 8.0. The following CVEs are assigned: CVE-2026-18282.
AI Analysis
Technical Summary
CVE-2026-18282 is a heap-based buffer overflow vulnerability in the handling of AVRCP packets on Sony XAV-9500ES devices. An attacker must first pair a malicious Bluetooth device with the target system to exploit this flaw. The vulnerability results from insufficient validation of the length of user-supplied data before copying it into a heap buffer, enabling remote code execution in the device's context. The Zero Day Initiative assigned this vulnerability a CVSS score of 8.0. Sony has released an update to fix this issue.
Potential Impact
Successful exploitation allows an attacker with Bluetooth pairing capability to execute arbitrary code remotely on affected Sony XAV-9500ES devices. This can lead to full compromise of the device, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Sony has issued an official update to correct this vulnerability. Users and administrators should apply the provided update from Sony's support site to remediate this issue. No additional mitigation steps are indicated by the vendor advisory.
