Security readout for executives and security teams
Plain-English summary
This CVE describes a flaw in a driver included with Advanced SystemCare Ultimate 11.0.1.58. A local user could crash the machine with a BSOD. The public record also says unspecified other impact may be possible, but does not confirm privilege escalation or remote attack.
Executive priority
Treat as a targeted endpoint stability risk, not a confirmed internet-facing emergency. Prioritize systems where local users run untrusted software, shared workstations, or critical endpoints where crashes disrupt operations.
Technical view
Monitor_win7_x64.sys does not validate input values sent through IOCTL 0x9c4060c4. The documented outcome is local denial of service through system crash, with other impact left unspecified. No CVSS, CWE, vendor advisory, or patch details are present in the supplied sources.
Likely exposure
Exposure appears limited to Windows systems where Advanced SystemCare Ultimate 11.0.1.58 installed and loads Monitor_win7_x64.sys. The attacker must already have local access or code execution on the host.
Exploitation context
The CVE references a public proof-of-concept repository for BSOD behavior. The source bundle does not show CISA KEV listing, active exploitation, remote exploitation, or confirmed privilege escalation.
Researcher notes
Evidence is sparse. The public description confirms an input-validation issue in a kernel driver and local BSOD impact. It does not provide a CVSS score, CWE mapping, affected CPEs, official vendor fix, or confirmed impact beyond denial of service.
Mitigation direction
- Identify systems running Advanced SystemCare Ultimate 11.0.1.58.
- Check whether Monitor_win7_x64.sys is present and loaded.
- Review vendor guidance for fixed versions or removal recommendations.
- Remove or disable the affected software where business need is absent.
- Restrict local user privileges on affected endpoints.
Validation and detection
- Inventory endpoint software versions for Advanced SystemCare Ultimate.
- Verify whether the named driver exists on in-scope hosts.
- Review crash telemetry for BSODs involving Monitor_win7_x64.sys.
- Confirm compensating controls limit local untrusted code execution.
- Track vendor or CVE updates for confirmed fixes.
