CVE-2026-23451
7.5
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
