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 46c7d9fe8dd869ea5de666aba8c1ec1061ca44a8; Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP to *; Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP to *; Siemens/SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP to *; Siemens/SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP to *; Siemens/SIPLUS S7-1500 CPU 1518-4 PN/DP MFP to *; Siemens/SIPLUS S7-1500 CPU 1518-4 PN/DP MFP to * 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: net: hns3: add VLAN id validation before using Currently, the VLAN id may be used without validation when receive a VLAN configuration mailbox from VF. The length of vlan_del_fail_bmap is BITS_TO_LONGS(VLAN_N_VID). It may cause out-of-bounds memory access once the VLAN id is bigger than or equal to VLAN_N_VID. Therefore, VLAN id needs to be checked to ensure it is within the range of VLAN_N_VID.
