This vulnerability can be exploited by an attacker with physical access to bypass existing security restrictions and gain access to encrypted data. Microsoft has disabled a fix for this issue due to firmware incompatibility problems that caused devices to enter BitLocker recovery mode. As a result, customers are advised to apply manual mitigations. Recommendations: To mitigate this issue, apply the manual mitigations advised by Microsoft, which require restarting the impacted device eight times. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
