A heap-based buffer overflow vulnerability exists in the Bluetooth AVRCP Profile protocol dissector of Wireshark versions 4.6.0 to 4.6.7 and 4.4.0 to 4.4.18. This flaw can cause the application to crash, resulting in a denial of service condition.
AI Analysis
Technical Summary
CVE-2026-76917 is a heap-based buffer overflow vulnerability (CWE-122) in the Bluetooth AVRCP Profile protocol dissector component of Wireshark. It affects versions 4.6.0 through 4.6.7 and 4.4.0 through 4.4.18. The vulnerability can be triggered by processing crafted Bluetooth AVRCP protocol data, leading to a crash of the Wireshark application and denial of service. The CVSS 3.1 base score is 5.5, indicating a medium severity with local attack vector, low attack complexity, no privileges required, user interaction required, and impact limited to availability.
Potential Impact
Successful exploitation causes denial of service by crashing the Wireshark application when parsing malicious Bluetooth AVRCP Profile protocol data. There is no confidentiality or integrity impact reported. No known exploits are currently in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links have been provided at this time. Users should avoid opening untrusted Bluetooth AVRCP traffic in affected Wireshark versions. Monitor the Wireshark Foundation advisories for updates and apply patches once available.
