CVE-2026-7376 Details
Description
Crash in sharkd 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
A denial-of-service vulnerability has been identified in the Wireshark sharkd utility, specifically in versions 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14. The issue arises from a NULL pointer dereference in the 'setcomment' method, where the comment parameter is optional. When omitted, it leads to a crash by causing a read access violation. This vulnerability can be exploited by sending a malformed JSON-RPC request that omits the comment parameter, causing sharkd to crash when the missing value is processed.
Users are advised to upgrade to Wireshark versions 4.6.5, 4.4.15 or later.
