CVE-2026-23451
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
