The vulnerability of the tpm_read_log_acpi() function in the drivers/char/tpm/eventlog/acpi.c file of the Linux operating system’s TPM-based character device driver allows a attacker to cause a service failure.

The vulnerability of the tpmreadlogacpi function in the drivers/char/tpm/eventlog/acpi.c file of the Linux operating system’s TPM-enabled character device driver is related to improper memory release. Exploiting this vulnerability could allow an attacker to cause a service failure...

kernel: tpm: acpi: Call acpi_put_table() to fix memory leak

In the Linux kernel, the following vulnerability has been resolved: tpm: acpi: Call acpiputtable to fix memory leak The start and length of the event log area are obtained from TPM2 or TCPA table, so we call acpigettable to get the ACPI information, but the acpigettable should be coupled with...
