CVE-2025-11678 (GCVE-0-2025-11678)

Vulnerability from cvelistv5 – Published: 2025-10-20 13:51 – Updated: 2025-10-20 14:00

Title

Stack-based Buffer Overflow in libwebsockets DNS response parsing

Summary

Stack-based Buffer Overflow in lws_adns_parse_label in warmcat libwebsockets allows, when the LWS_WITH_SYS_ASYNC_DNS flag is enabled during compilation, to overflow the label_stack, when the attacker is able to sniff a DNS request in order to craft a response with a matching id containing a label longer than the maximum.

Severity ?

7.5 (High)
