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 exists in the FMP/NOTIFY protocol dissector where unchecked input is used as a loop condition, leading to a crash and 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 currently indicated in the available data.
Potential Impact
Successful exploitation causes a denial of service by crashing the Wireshark application when processing crafted FMP/NOTIFY protocol data. There is no reported impact on confidentiality or integrity, only availability is affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when analyzing untrusted FMP/NOTIFY protocol traffic to avoid triggering the crash.
