Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Siemens/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem.
  2. 2Review the reported fix. Update Linux/Linux to e7ea60184e1e88a3c9e437b3265cbb6439aa7e26; Siemens/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem to *; Siemens/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem to V1.1.1 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: HID: core: zero-initialize the report buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted report.
