Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP.
  2. 2Review the reported fix. Update Linux/Linux to a6411f3c48f991c19aaf9a24fce36865fbba28d7; Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP to V3.1.5; Siemens/SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP to V3.1.5; Siemens/SIPLUS S7-1500 CPU 1518-4 PN/DP MFP to V3.1.5 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: set dormant flag on hook register failure We need to set the dormant flag again if we fail to register the hooks. During memory pressure hook registration can fail and we end up with a table marked as active but no registered hooks. On table/base chain deletion, nf_tables will attempt to unregister the hook again which yields a warn splat from the nftables core.
