Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Siemens/RUGGEDCOM RST2428P.
  2. 2Review the reported fix. Update Linux/Linux to 40f1d79f07b49c8a64a861706e5163f2db4bd95d; Siemens/RUGGEDCOM RST2428P to V3.1; Siemens/SCALANCE XCM-/XRM-/XCH-/XRH-300 family to V3.1; 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: i2c: smbus: fix NULL function pointer dereference Baruch reported an OOPS when using the designware controller as target only. Target-only modes break the assumption of one transfer function always being available. Fix this by always checking the pointer in __i2c_transfer. [wsa: dropped the simplification in core-smbus to avoid theoretical regressions]
