CVE-2026-95395: CWE-401: Missing Release of Memory after Effective Lifetime in Wireshark Foundation Wireshark
IEEE C37.118 Synchrophasor protocol dissector memory leak in 4.6.0 to 4.6.8 and 4.4.0 to 4.4.18 allows denial of service
AI Analysis
Technical Summary
This vulnerability is a memory leak (CWE-401) in the IEEE C37.118 Synchrophasor protocol dissector component of Wireshark versions 4.4.0 to 4.4.18 and 4.6.0 to 4.6.8. The leak occurs because memory allocated during packet processing is not properly released after use, potentially allowing an attacker to cause a denial of service by exhausting system memory. The CVSS 3.1 base score is 5.5 (medium), with attack vector local, low attack complexity, no privileges required, user interaction required, and impact limited to availability.
Potential Impact
Successful exploitation can cause denial of service by exhausting memory resources on the host running Wireshark, potentially causing the application to crash or become unresponsive. There is no confidentiality or integrity impact reported. The attack requires local access and user interaction.
Mitigation Recommendations
No official patch or fix information is provided in the input data. Patch status is not yet confirmed — check the Wireshark Foundation advisory or official sources for current remediation guidance. Until a fix is available, avoid processing untrusted IEEE C37.118 Synchrophasor protocol traffic or use alternative tools.
