AI Analysis
Technical Summary
CVE-2026-15163 identifies multiple infinite loop vulnerabilities in Wireshark protocol dissectors affecting versions 4.6.0 and 4.4.0. These infinite loops occur due to unreachable exit conditions in the code, leading to denial of service by causing the application to hang or become unresponsive during packet analysis. The vulnerability is classified under CWE-835 (Loop with Unreachable Exit Condition). There is no vendor advisory or patch information available, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation of this vulnerability can cause Wireshark to enter an infinite loop, resulting in denial of service by making the application unresponsive. There is no impact on confidentiality or integrity reported.
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 network traffic with affected versions.
