CVE-2022-50562

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> tpm: acpi: Call acpi_put_table() to fix memory leak<br /> <br /> The start and length of the event log area are obtained from<br /> TPM2 or TCPA table, so we call acpi_get_table() to get the<br /> ACPI information, but the acpi_get_table() should be coupled with<br /> acpi_put_table() to release the ACPI memory, add the acpi_put_table()<br /> properly to fix the memory leak.<br /> <br /> While we are at it, remove the redundant empty line at the<br /> end of the tpm_read_log_acpi().
