Vulnerability from fkie_nvd - Published: 2024-04-28 13:15 - Updated: 2026-06-17 05:15
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: net: sched: fix possible refcount leak in tc_new_tfilter() tfilter_put need to be called to put the refount got by tp->ops->get to avoid possible refcount leak when chain->tmplt_ops != NULL and chain->tmplt_ops != tp->ops.
