The US government Cybersecurity and Infrastructure Security Agency (CISA) is one of my go to resources for cyber security information – particularly when it comes to patching vulnerable products.
Cisco Releases Security Advisories for Multiple Products – CISA
CISA also releases industrial control system advisories – if you are responsible for these types of systems you should monitor their news page:
My advice: Either you or your IT support need to check whether these issues impact your systems. You need to have a master document that details your systems, hardware, software, online, networks, back-ups, suppliers etc – so when cyber security (or operational) issues arise you and your support teams can quickly check if you are affected. From there you can take fast, effective action.
