CVE-2025-32743
Last modified
CVE-2025-32743 is a critical-severity vulnerability rated 9/10 on the CVSS scale. 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.. EPSS estimates a 0.42% chance of exploitation in the next 30 days.
