TL;DR: Unosecur says Microsoft’s May 2025 Patch Tuesday bundled 72 fixes, seven zero-days, and multiple flaws that can convert a local foothold into SYSTEM control, token theft, or Entra ID telemetry blind spots. Patch cadence now functions as identity governance because exploit chains increasingly target the credentials and service principals that identity programmes are supposed to protect.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “May Patch Tuesday: Zero-Days & Identity Risks”.
Key questions
Q: What breaks when Patch Tuesday zero-days are treated as ordinary vulnerability work?
A: Identity governance breaks first, because local code execution or privilege escalation can expose the tokens, service principals, and telemetry channels that IAM depends on.
Q: Why do kernel or scripting zero-days create identity risk in cloud environments?
A: They matter because the compromised host often already contains authenticated context, cached secrets, or trust relationships into Azure, Entra, or CI/CD systems.
Q: How do teams know if identity telemetry is still trustworthy after patching?
A: They should test whether alerts, sensor output, and correlation logic still distinguish normal behaviour from spoofed or manipulated events.
Practitioner guidance
- Prioritise identity-adjacent zero-days first Rank Patch Tuesday items by whether the vulnerable system can reach tokens, service principals, build pipelines, or directory-connected workloads.
- Tie patch status to access decisions Feed patch compliance into access governance so risky, unpatched hosts lose or never gain access to sensitive identity resources until the exposure is removed.
- Harden identity telemetry against spoofing Validate the trust path for sensor data, watch for inconsistent account behaviour, and treat spoofing against identity monitoring as a control failure rather than a simple alerting issue.
Bottom line: Patch Tuesday matters to identity teams because local exploits can become SYSTEM-level access, token theft, or telemetry manipulation in a single chain.

Patch management is now an identity governance control, not just a vulnerability hygiene task. When zero-days can lead directly to SYSTEM, token theft, or spoofed identity telemetry, the boundary between infrastructure remediation and identity governance no longer holds. Organisations that treat Patch Tuesday as a separate ops function are preserving an attack path that identity teams will later be asked to explain. The practical conclusion is that patch cadence must be governed as part of the identity programme, not adjacent to it.
A few things that frame the scale:
- CrowdStrike's 2026 Global Threat Report said zero-days exploited before public disclosure rose 42% year over year.
A question worth separating out:
A: They should do both, but identity hardening often limits the fastest spread while patching addresses the root entry point. If the exploit path already includes SSO, tokens, or privileged credentials, revocation and containment can reduce impact before the patch cycle completes.
