New TPM 2.0 Flaws Could Let Hackers Steal Cryptographic Keys
The Trusted Platform Module (TPM) 2.0 specification is affected by two buffer overflow vulnerabilities that could allow attackers to access or overwrite sensitive data, such as cryptographic keys.
TPM is a hardware-based technology that provides operating systems with tamper-resistant secure cryptographic functions. It can be used to store cryptographic keys, passwords, and other critical data, making any vulnerability in its implementation a cause for concern.
While a TPM is required for some Windows security features, such as Measured Boot, Device Encryption, Windows Defender System Guard (DRTM), Device Health Attestation, it is not required for other more commonly used features.
However, when a Trusted Platform Module is available, Windows security features get enhanced security in protecting sensitive information and encrypting data.
The TPM 2.0 specification gained popularity (and controversy) when Microsoft made it a requirement for running Windows 11 due to its required boot security measures and ensuring that Windows Hello face recognition provides reliable authentication.
Linux also supports TPMs, but there are no requirements for using the module in the operating system. However, there are Linux tools available that allow applications and users to secure data in TPMs.
