- Summary
- tpm: Use auth only after NULL check in tpm_buf_check_hmac_response()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
tpm: Use auth only after NULL check in tpmbufcheckhmacresponse()
Dereference auth after NULL check in tpmbufcheckhmacresponse(). Otherwise, unless tpm2sessionsinit() was called, a call can cause NULL dereference, when TCGTPM2HMAC is enabled.
