CVE-2026-10028 | BDVDB-2026-336113 Detail

Red HatRed Hat Enterprise Linux 10

Description#

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.

Impact#

Per CVSS v3.1: confidentiality impact none, integrity impact none, availability impact low. Attack vector: network.
