Sony XAV-AX8500 Bluetooth L2CAP Protocol Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Sony XAV-AX8500 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 implementation of the Bluetooth L2CAP protocol. 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 elysian-bt-service process. Was ZDI-CAN-26286.
AnalysisAI
A remote code execution vulnerability (CVSS 7.5) that allows network-adjacent attackers. High severity vulnerability requiring prompt remediation. Vendor patch is available.
Technical ContextAI
CWE-122 (Heap-based Buffer Overflow). CVSS 7.5 indicates high severity.
RemediationAI
Apply the vendor-supplied patch immediately. Consider network segmentation to limit exposure if patching is delayed.
