CVE-2023-26596· NVD / CVE Program· CNA intel

Improper access control in some Intel(R) Thunderbolt(TM) DCH drivers for Windows before version 88 may allow an authenticated user to potent

Noroxi assessment

Priority: Monitor (action score 10/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.15% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • According to the record, no fixed version is available yet.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Improper access control in some Intel(R) Thunderbolt(TM) DCH drivers for Windows before version 88 may allow an authenticated user to potentially enable denial of service via local access.
