Overview

CVE-2024-53085 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 19, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

tpm: Lock TPM chip in tpm_pm_suspend() first

Setting TPM_CHIP_FLAG_SUSPENDED in the end of tpm_pm_suspend() can be racy

according, as this leaves window for tpm_hwrng_read() to be called while

the operation is in progress. The recent bug report gives also evidence of

this behaviour.

Aadress this by locking the TPM chip before checking any chip->flags both

in tpm_pm_suspend() and tpm_hwrng_read(). Move TPM_CHIP_FLAG_SUSPENDED

check inside tpm_get_random() so that it will be always checked only when

the lock is reserved.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
