A flaw was found in the Linux kernel's Trusted Platform Module (TPM) subsystem. This vulnerability allows an attacker to bypass TPM reset protections because the driver fails to disable the device when a null key integrity check fails. Consequently, the TPM continues serving requests and cryptographic authorization sessions may proceed using uninitialized key handles, compromising the integrity of secure operations.
