CVE-2026-95389: CWE-122: Heap-based Buffer Overflow in Wireshark Foundation Wireshark
SCTP 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 involves a heap-based buffer overflow in the SCTP protocol dissector component of Wireshark. It affects versions from 4.4.0 up to but not including 4.4.19 and from 4.6.0 up to but not including 4.6.9. The flaw can be triggered by malformed SCTP packets, causing the Wireshark application to crash, leading to denial of service. The CVSS 3.1 base score is 8.1, indicating high severity, with network attack vector, high attack complexity, no privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.
Potential Impact
An attacker can cause Wireshark to crash by sending specially crafted SCTP packets, resulting in denial of service. The vulnerability affects confidentiality, integrity, and availability as indicated by the CVSS vector, but the primary impact described is denial of service due to application crash.
Mitigation Recommendations
No explicit patch or remediation details are provided in the input data. Patch status is not yet confirmed — check the Wireshark Foundation vendor advisory for current remediation guidance. Users should monitor official Wireshark channels for updates and apply patches once available.
