Summary

In the Linux kernel, the tpm_crb driver lacked a check of ACPI_COMPANION() against NULL during probe. This check was added to prevent issues when a device has no ACPI companion object.

Risk Assessment

Lack of check can lead to crashes or malfunction of the driver, potentially affecting TPM-based security features.

Recommendation

Apply the Linux kernel patch that adds a check of ACPI_COMPANION() against NULL in the tpm_crb driver.

Original NVD description (English source)

In the Linux kernel, the following vulnerability has been resolved: tpm_crb: Check ACPI_COMPANION() against NULL during probe Every platform driver can be forced to match a device that doesn't match its list of device IDs because of device_match_driver_override(), so platform drivers that rely on the existence of a device's ACPI companion object need to verify its presence. Accordingly, add a requisite ACPI_COMPANION() check against NULL to the tpm_crb driver.
