Technical Summary
This vulnerability (CWE-125) in Wireshark's Bluetooth HFP Profile protocol dissector allows an out-of-bounds read that leads to a crash of the application. The affected versions are specifically 4.4.0 through 4.4.18 and 4.6.0 through 4.6.7. The flaw can be triggered by processing crafted Bluetooth HFP traffic, causing denial of service due to application crash. There is no vendor advisory or patch information available yet, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation results in denial of service by crashing the Wireshark application when it processes malicious Bluetooth HFP Profile protocol data. There is no impact on confidentiality or integrity reported. The attack vector requires local access (AV:L) and user interaction (UI:R).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid analyzing untrusted Bluetooth HFP traffic with affected versions of Wireshark to reduce risk of denial of service.
