A Microsoft lançou seu Patch Tuesday de novembro de 2025, corrigindo 63 vulnerabilidades, incluindo uma falha de dia zero de alta prioridade que está sendo explorada atualmente. Esta atualização crucial fornece cinco correções críticas e 64 importantes, vitais para as organizações fortalecerem suas defesas.

O Atualizações abrangem produtos importantes como SQL Server, Windows Hyper-V, Visual Studio, Windows Kernel, Windows WLAN Service e muito mais.

Um patch crítico é necessário para uma vulnerabilidade de dia zero no kernel do Windows: CVE-2025-62215. Essa vulnerabilidade de Elevação de Privilégio (EoP) pode permitir que um invasor autenticado obtenha privilégios SYSTEM explorando uma condição de corrida.

Existem quatro outras falhas de gravidade crítica junto com o dia zero, que representam sérios riscos de Execução Remota de Código (RCE) ou Elevação de Privilégio (EoP) de alto nível.

Uma grande falha, CVE-2025-30398, no Nuance PowerScribe 360 representa um sério risco de divulgação de informações. Ele surge da falta de autorização no sistema, permitindo que invasores não autenticados o explorem por meio de uma chamada de API específica, potencialmente revelando informações confidenciais do servidor.

A Microsoft também incluiu Correções para cinco Vulnerabilidades em seu navegador Edge baseado em Chromium.

Dada a exploração ativa do dia zero do kernel do Windows, as equipes de TI devem priorizar e implantar esses patches de segurança imediatamente.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).

Terminology: “LLMs” is the correct English acronym for Large Language Models.
