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.

acpi_put_table() should be added to release the ACPI memory.
A memory leak flaw was found in the Linux kernel's TPM TIS driver. The check_acpi_tpm2() function retrieves the TPM2 ACPI table to verify its presence but fails to release the table reference via acpi_put_table(), resulting in a memory leak each time the function is called during driver initialization.
Statement: This is a one-time memory leak that occurs during TPM driver initialization. The leaked memory is sma
