CVE-2025-32743

CRITICAL

9.0

CVSS v3

NVD

Description

In ConnMan through 1.44, the lookup string in ns_resolv in dnsproxy.c can be NULL or an empty string when the TC (Truncated) bit is set in a DNS response. This allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code, because those lookup values lead to incorrect length calculations and incorrect memcpy operations.
