Microsoft’s public record for CVE‑2026‑21508 places this as another entry in a familiar—and dangerous—class of Windows kernel vulnerabilities: an elevation‑of‑privilege (EoP) issue tied to the Windows storage virtualization stack. The vendor’s Security Update Guide entry confirms the...

Microsoft’s security registry records CVE-2026-20838 as a Windows kernel information‑disclosure vulnerability — an advisory IT teams must treat as a credible reconnaissance primitive that can materially aid follow‑on local exploitation unless systems are patched and detection controls are...

Microsoft’s advisory identifies CVE-2026-20809 as a time-of-check/time-of-use (TOCTOU) race condition in Windows kernel memory that can be abused by an authorized local user to gain SYSTEM privileges — in short, a local elevation-of-privilege (EoP) vulnerability rooted in kernel memory...

Microsoft’s own engineers have announced an audacious, company-wide plan: use AI and large-scale automated tooling to translate Microsoft’s C and C++ codebases to Rust — with an explicit target of eliminating “every line of C and C++ from Microsoft by 2030.” Background Microsoft’s shift toward...

CISA’s decision to add three fresh entries to its Known Exploited Vulnerabilities (KEV) Catalog marks another urgent reminder that attackers are continuing to weaponize both edge devices and enterprise software against unpatched targets — and that federal agencies and private organizations alike...

Microsoft confirmed a Windows kernel elevation‑of‑privilege vulnerability tracked as CVE‑2025‑59194, describing it as a use of uninitialized resource in kernel code that an authorized local attacker can exploit to gain elevated privileges; Microsoft published the advisory and security update...
