CVE-2023-27308

Vulnerability

An improper buffer restrictions vulnerability exists in some Intel(R) Thunderbolt(TM) DCH drivers for Windows before version 88. This flaw can be exploited by a privileged user to achieve escalation of privilege via local access. The affected driver versions are those prior to the 88 release. [1]

Exploitation

An attacker needs local access and a certain level of privilege on the system to exploit this vulnerability. The exact sequence of steps is not detailed in the available references, but the improper buffer restriction could be triggered by a specially crafted input or operation that interacts with the Thunderbolt driver. [1]

Impact

Successful exploitation of this vulnerability allows an attacker to escalate privileges on the affected system. This means the attacker could gain higher-level access, potentially leading to full control of the system, including the ability to execute arbitrary code with elevated privileges, install programs, or modify data. [1]

Mitigation

The vulnerability is fixed in Intel Thunderbolt DCH driver version 88 and later. Users should update to the latest driver version available from Intel. Intel's security advisory (INTEL-SA-00851) provides further guidance. [1]
