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.

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2914-1 advisory.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2026-23451)

Note that Nessus relies on the presence of the package as reported by the vendor.
