CVE-2026-6525: CWE-476: NULL Pointer Dereference in Wireshark Foundation Wireshark
CVE-2026-6525 is a medium severity vulnerability in Wireshark versions 4. 6. 0 to 4. 6. 4 where the IEEE 802. 11 protocol dissector can cause a crash due to a NULL pointer dereference. This results in a denial of service condition when the application attempts to process certain malformed packets. There is no confirmed patch or official remediation available at this time, and no known exploits have been reported in the wild.
AI Analysis
Technical Summary
This vulnerability involves a NULL pointer dereference (CWE-476) in the IEEE 802.11 protocol dissector component of Wireshark versions 4.6.0 through 4.6.4. When processing specific malformed network packets, Wireshark may crash, leading to a denial of service. The CVSS 3.1 base score is 5.5, reflecting a medium severity with local attack vector, low complexity, no privileges required, user interaction needed, and impact limited to availability. No patch or official fix has been documented in the available data.
Potential Impact
Successful exploitation causes Wireshark to crash, resulting in denial of service. There is no impact on confidentiality or integrity according to the CVSS vector. No known exploits are reported in the wild, so the threat is currently theoretical.
Mitigation Recommendations
Patch status is not yet confirmed — check the Wireshark Foundation advisory for current remediation guidance. Until a fix is available, users should exercise caution when analyzing untrusted IEEE 802.11 traffic and consider avoiding use of affected versions if possible.
