CVE-2026-95392: CWE-126: Buffer Over-read in Wireshark Foundation Wireshark
MBIM protocol dissector crash 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 buffer over-read (CWE-126) in the MBIM protocol dissector component of Wireshark versions 4.4.0 to 4.4.18 and 4.6.0 to 4.6.8. The flaw allows crafted input to cause the dissector to read beyond the intended buffer boundaries, leading to a crash of the Wireshark application and denial of service. The CVSS 3.1 base score is 5.5, reflecting a local attack vector with low complexity, no privileges required, and user interaction needed, impacting availability only.
Potential Impact
Successful exploitation results in denial of service by crashing Wireshark when processing malicious MBIM protocol packets. There is no impact on confidentiality or integrity. The attack requires local access and user interaction.
Mitigation Recommendations
No explicit patch or remediation details are provided in the available data. Users should upgrade to versions later than 4.4.18 and 4.6.8 once official fixes are released. Until then, avoid processing untrusted MBIM protocol traffic with affected versions. Monitor the Wireshark Foundation advisories for official patches.
