NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-modules package and not the kernel-64k-debug-modules package as distributed by RHEL.

In the Linux kernel, the following vulnerability has been resolved:

net_sched: ets: Fix double list add in class with netem as child qdisc

As described in Gerrard's report [1], there are use cases where a netem child qdisc will make the parent qdisc's enqueue callback reentrant. In the case of ets, there won't be a UAF, but the code will add the same classifier to the list twice, which will cause memory corruption.

In addition to checking for qlen being zero, this patch checks whether the class was already added to the active_list (cl_is_active) before doing the addition to cater for the reentrant case.
