Recommendation: Monitor — no exploitation signal at the moment.
In the Linux kernel, the following vulnerability has been resolved: tpm: acpi: Call acpi_put_table() to fix memory leak The start and length of the event log area are obtained from TPM2 or TCPA table, so we call acpi_get_table() to get the ACPI information, but the acpi_get_table() should be coupled with acpi_put_table() to release the ACPI memory, add the acpi_put_table() properly to fix the memory leak. While we are at it, remove the redundant empty line at the end of the tpm_read_log_acpi().
