In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak In check_acpi_tpm2(), we get the TPM2 table just to make sure the table is there, not used after the init, so the acpi_put_table() should be added to release the ACPI memory.
