CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of the neighbour hardware address (n->ha) within the vxlan module, where asynchronous updates can lead to torn reads or partially updated MAC addresses due to inadequate locking mechanisms. This could potentially compromise network integrity and stability. Organizations utilizing Linux systems with vxlan configurations should prioritize addressing this issue to mitigate risks associated with network communication errors.
Original NVD Description
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.
