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 afd5730969aec960a2fee4e5ee839a6014643976; Siemens/RUGGEDCOM RST2428P to V3.1; Siemens/SCALANCE XCM-/XRM-/XCH-/XRH-300 family to V3.1; 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/SIMATIC S7-1500 TM MFP - GNU/Linux subsystem to V1.1.1; 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: ipv6: sr: fix memleak in seg6_hmac_init_algo seg6_hmac_init_algo returns without cleaning up the previous allocations if one fails, so it's going to leak all that memory and the crypto tfms. Update seg6_hmac_exit to only free the memory when allocated, so we can reuse the code directly.
