Glib-Networking GnuTLS Cert Verification Infinite Loop DoS
CVE-2026-10028 Published on May 28, 2026
Glib-networking: infinite loop in glib-networking gnutls backend allows remote denial of service via circular certificate chain
A flaw was found in glib-networking. A remote attacker can exploit this vulnerability by presenting a specially crafted certificate chain to an application that uses glib-networking with the GnuTLS backend enabled and performs certificate verification. This crafted chain, which contains circular issuer relationships, can cause an infinite loop during certificate verification. The unbounded traversal consumes excessive CPU resources, leading to a denial of service for the affected process or worker.
