CVE-2025-37913

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, related to the net sched component, specifically the qfq queueing discipline. The issue arises when a netem child qdisc causes the parent qdisc's enqueue callback to become reentrant, leading to memory corruption due to adding the same classifier to the list twice. This is fixed by checking if the class was already added to the agg->active list before doing the addition.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
