Security readout for executives and security teams
Plain-English summary
A locally authenticated attacker with limited privileges could exploit a timing flaw in Windows Perception Service to gain elevated access. Successful exploitation could compromise sensitive data, alter the system, or disrupt availability. The attack is not remotely exploitable according to the supplied CVSS vector and requires high attack complexity.
Executive priority
Treat this as a high-priority patching issue, especially on multi-user systems and servers where local access is plausible. It is less urgent than an unauthenticated remote compromise, but successful exploitation could produce complete system-level confidentiality, integrity, and availability impact.
Technical view
CVE-2024-35265 is a CWE-367 time-of-check/time-of-use race condition in Windows Perception Service. Its CVSS 3.1 score is 7.0: local access, high complexity, low privileges, no user interaction, unchanged scope, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure includes the listed Windows 10, Windows 11, Windows Server 2019, and Server Core versions. Exploitation requires local access and low privileges. The sources do not identify additional configuration prerequisites, so asset inventory and Microsoft advisory checks are necessary.
Exploitation context
The supplied bundle does not establish active exploitation, and the CVE is not marked as CISA KEV. CVSS reports exploit maturity as unknown. This does not prove exploitation is absent; it means the cited evidence provides no confirmation.
Researcher notes
The evidence supports a local, high-complexity privilege-escalation race condition, but does not describe the vulnerable code path, required timing conditions, resulting privilege level, public proof of concept, or observed attacks. Validate conclusions against Microsoft’s advisory and avoid inferring unsupported prerequisites.
Mitigation direction
- Review Microsoft’s CVE advisory and deploy the applicable security updates.
- Prioritize shared workstations, servers, and systems where untrusted users can obtain local access.
- Restrict unnecessary local accounts and privileges while updates are pending.
- Check Microsoft guidance for any product-specific mitigations or prerequisites.
Validation and detection
- Inventory systems running the affected Windows products and versions.
- Confirm each system has the Microsoft update applicable to CVE-2024-35265 installed.
- Re-scan updated assets using current authenticated vulnerability checks.
- Document systems lacking updates, including ownership, exposure, and remediation deadlines.

Time-of-check Time-of-use (TOCTOU) Race Condition
Time-of-check Time-of-use (TOCTOU) Race Condition represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
