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_router: Fix neighbour
 use-after-free We sometimes observe use-after-free when dereferencing a neighbour [1]. The problem seems
 to be that the driver stores a pointer to the neighbour, but without holding a reference on it. A
 reference is only taken when the neighbour is used by a nexthop. Fix by simplifying the reference counting
 scheme. Always take a reference when storing a neighbour pointer in a neighbour entry. Avoid taking a
 referencing when the neighbour is used by a nexthop as the neighbour entry associated with the nexthop
 already holds a reference. Tested by running the test that uncovered the problem over 300 times. Without
 this patch the problem was reproduced after a handful of iterations. [1] BUG: KASAN: slab-use-after-free
