Title
tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak
Summary
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.
Severity ?
No CVSS data available.
