CVE-2026-23451

Description

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

bonding: prevent potential infinite loop in bond_header_parse()

bond_header_parse() can loop if a stack of two bonding devices is setup, because skb->dev always points to the hierarchy top.

Add new "const struct net_device *dev" parameter to (struct header_ops)->parse() method to make sure the recursion is bounded, and that the final leaf parse method is called.
