114 Updates, 1 Active Exploit — January Patch Tuesday: Patch Today or Pay Tomorrow

Episode notes

Hosted by Graham Falkner, this episode is a rapid, no‑nonsense January Patch Tuesday breakdown aimed at small businesses and IT owners. Graham walks listeners through Microsoft’s unusually large release of 114 security updates, explains the essential jargon (CVE and CVSS), and highlights why severity scores don’t replace real‑world risk assessments. The show covers the one vulnerability already being actively exploited (CVE‑2026‑2805 in Desktop Window Manager) and two other high‑risk items used in targeted attacks, plus three zero‑day bugs. Graham takes a deep dive into the critical on‑premises SharePoint emergency (Toolshell campaign, CVE‑2025‑53‑700‑70 and related issues), urging immediate patching and incident response for exposed servers. He also explains the severe Kestrel/ASP.NET Core HTTP request smuggling flaw (CVE‑2025‑55315) and the practical impact on web apps and deployment teams.
