CVE-2023-27307

Vulnerability

An improper buffer restrictions vulnerability exists in some Intel(R) Thunderbolt(TM) DCH drivers for Windows before version 88 [1]. The flaw resides in the driver's handling of buffer boundaries, potentially allowing an authenticated user to trigger an information disclosure via local access [1].

Exploitation

An attacker must have local access to the system and be authenticated [1]. No specific sequence of steps is detailed, but the improper buffer restriction can be triggered by a crafted application or process that interacts with the vulnerable driver component [1].

Impact

Successful exploitation allows the attacker to achieve information disclosure, potentially exposing sensitive data from kernel memory or other protected areas [1]. The scope is limited to local access, not remote exploitation.

Mitigation

Intel released driver version 88 to address this issue [1]. Users should update to the latest Intel Thunderbolt DCH driver version for Windows [1]. No workarounds were provided in the advisory [1].
