Descriptions

In the Linux kernel, the following vulnerability has been resolved:

tpm: Use auth only after NULL check in tpm_buf_check_hmac_response()

Dereference auth after NULL check in tpm_buf_check_hmac_response().
Otherwise, unless tpm2_sessions_init() was called, a call can cause NULL
dereference, when TCG_TPM2_HMAC is enabled.

[jarkko: adjusted the commit message.]

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tpm: use autenticación solo después de la verificación NULL en tpm_buf_check_hmac_response() Desreferenciar la autenticación después de la verificación NULL en tpm_buf_check_hmac_response(). De lo contrario, a menos que se haya llamado a tpm2_sessions_init(), una llamada puede causar una desreferencia NULL, cuando TCG_TPM2_HMAC está habilitado. [jarkko: ajustó el mensaje de confirmación.]
