How to fix?

Upgrade RHEL:9 gnutls-utils to version 0:3.8.10-4.el9_8 or higher.
This issue was patched in RHSA-2026:20612.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gnutls-utils package and not the gnutls-utils package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service.
