Summary

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

mlxsw: spectrum_mr: Fix use-after-free when updating multicast route stats

Cited commit added a dedicated mutex (instead of RTNL) to protect the multicast route list, so that it will not change while the driver periodically traverses it in order to update the kernel about multicast route stats that were queried from the device.

One instance of list entry deletion (during route replace) was missed and it can result in a use-after-free [1].

Fix by acquiring the mutex before deleting the entry from the list and releasing it afterwards.
