Technical Analysis
This vulnerability involves an out-of-bounds read (CWE-125) in the Bluetooth Attribute Protocol dissector component of Wireshark. Affected versions include 4.4.0 up to and including 4.4.18, and 4.6.0 up to and including 4.6.7. The flaw allows crafted Bluetooth packets to trigger a crash in Wireshark, causing denial of service. The CVSS 3.1 vector indicates the attack requires local access with high attack complexity and user interaction, and it does not impact confidentiality or integrity but affects availability.
Potential Impact
Successful exploitation causes Wireshark to crash, leading to denial of service. There is no impact on confidentiality or integrity. The attack requires local access, high complexity, and user interaction, limiting the ease of exploitation.
Mitigation Recommendations
No explicit patch or remediation information is provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted Bluetooth traffic with affected versions of Wireshark.
