CVE-2026-15172: CWE-606: Unchecked Input for Loop Condition in Wireshark Foundation Wireshark
A vulnerability in the FMP/NOTIFY protocol dissector of Wireshark versions 4.6.0 to 4.6.6 and 4.4.0 to 4.4.16 allows a denial of service condition due to unchecked input for a loop condition. This can cause the application to crash when processing crafted packets.
AI Analysis
Technical Summary
CVE-2026-15172 is a medium severity vulnerability in Wireshark Foundation's Wireshark software affecting versions 4.6.0 through 4.6.6 and 4.4.0 through 4.4.16. The flaw is due to unchecked input used as a loop condition in the FMP/NOTIFY protocol dissector, which can lead to a crash and thus a denial of service. The CVSS 3.1 base score is 5.5, reflecting local attack vector, low complexity, no privileges required, user interaction required, unchanged scope, no confidentiality or integrity impact, and high availability impact. No official patch or remediation level is indicated in the available data, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation causes a denial of service by crashing Wireshark when processing maliciously crafted FMP/NOTIFY protocol packets. There is no impact on confidentiality or integrity. The attack requires local access and user interaction (opening a crafted capture file).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid opening untrusted capture files containing FMP/NOTIFY protocol data. Monitor Wireshark updates for a security patch addressing this issue.
