Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-62215 is a race condition vulnerability (CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization (Race Condition); CWE-415: Double Free) in the Windows Kernel. Published on 2025-11-11T18:15:48.920, it carries a CVSS v3.1 base score of 7.0 (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). The flaw arises from improper synchronization during concurrent access to a shared resource in the kernel, enabling local privilege escalation for authorized attackers.
A local attacker with low privileges (PR:L) can exploit this vulnerability by triggering the race condition, which requires high attack complexity (AC:H) but no user interaction (UI:N). Successful exploitation grants high-impact confidentiality, integrity, and availability compromises (C:H/I:H/A:H) without changing scope (S:U), typically resulting in elevated privileges on the affected Windows system.
Microsoft's update guide at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-62215 details patches and mitigation steps. The vulnerability is also listed in CISA's Known Exploited Vulnerabilities Catalog at https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2025-62215, signaling active real-world exploitation.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation explicitly includes dynamic analysis and fuzzing that locate double-free defects before release.
Security engineering principles can require memory-safe allocation patterns or language features that structurally eliminate double-free opportunities.
Maintaining separate execution domains for each process structurally eliminates unintended concurrent access to the same shared resources.
Preventing unintended information transfer through shared system resources directly addresses the improper concurrent modification that defines a race condition.
Flaw remediation processes require identification and correction of memory-management defects such as double free once discovered.

Security testing can detect race conditions, but does not prevent them at design or coding time.
Secure SDLC mandates concurrency controls and synchronization primitives that directly prevent race conditions.
Application security requirements can specify thread-safety and locking rules, but do not prescribe implementation details.
Secure architecture principles require proper synchronization and resource isolation, addressing the root cause of CWE-362.
Secure coding standards explicitly forbid unsafe concurrent access patterns and mandate atomic operations or locks.
Change management reduces introduction of concurrency bugs during updates, yet does not address the weakness itself.
