Description OSIDB Bzimport 2025-05-29 14:01:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

openvswitch: Fix unsafe attribute parsing in output_userspace()

This patch replaces the manual Netlink attribute iteration in
output_userspace() with nla_for_each_nested(), which ensures that only
well-formed attributes are processed.
