How to fix?

Upgrade SLES:15.6 kernel-obs-build to version 6.4.0-150600.23.135.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-obs-build package and not the kernel-obs-build package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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.
