The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-perf package and not the python3-perf package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
vxlan: fix reading neigh ha
Currently arp/neigh_reduce read neigh ha directly which can lead to partial reads while the neigh is being updated. Use neigh_ha_snapshot to take a stable snapshot of the address similar to route_shortcircuit which already does the right thing.
