--- title: CVE-2025-21971 description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2025-21971 --- # CVE-2025-21971 Publication date 1 April 2025 Last updated 12 October 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) ## Cvss 3 Severity Score **5.5 · Medium** [Score breakdown](https://ubuntu.com/security/CVE-2025-21971#impact-score) Toggle side navigation ## Description In the Linux kernel, the following vulnerability has been resolved: net\_sched: Prevent creation of classes with TC\_H\_ROOT The function qdisc\_tree\_reduce\_backlog() uses TC\_H\_ROOT as a termination condition when traversing up the qdisc tree to update parent backlog counters. However, if a class is created with classid TC\_H\_ROOT, the traversal terminates prematurely at this class instead of reaching the actual root qdisc, causing parent statistics to be incorrectly maintained. In case of DRR, this could lead to a crash as reported by Mingi Cho. Prevent the creation of any Qdisc class with classid TC\_H\_ROOT (0xFFFFFFFF) across all qdisc types, as suggested by Jamal. ## Status Show unmaintained releases | Package | Ubuntu Release | Status |
