+Subject: [PATCH] dnsproxy: Fix NULL/empty lookup causing potential crash
+
+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.
+
+This patch includes a check to make sure loookup value is valid before
+using it. This helps avoid unexpected value when the input is empty or
+incorrect.
+
+Fixes: CVE-2025-32743
