How to fix?

Upgrade SLES:16.0.0 kernel-obs-qa to version 6.12.0-160000.38.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-obs-qa package and not the kernel-obs-qa package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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

vxlan: use neigh_ha_snapshot() in route_shortcircuit()

The neighbour hardware address n->ha can be updated asynchronously by the neighbour subsystem, protected by n->ha_lock seqlock. Reading n->ha without holding the seqlock loop can lead to torn reads or reading a partially updated MAC address.

Use neigh_ha_snapshot() in route_shortcircuit() to safely copy n->ha under read_seqbegin()/read_seqretry() lock protection before using it.

Note that arp_reduce() and neigh_reduce() seem to have the same issue left for future patches.
