Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. [1] BUG: KASAN:
