Overview

CVE-2024-46692 is a medium-severity vulnerability. It was published on September 13, 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:

firmware: qcom: scm: Mark get_wq_ctx() as atomic call

Currently get_wq_ctx() is wrongly configured as a standard call. When two

SMC calls are in sleep and one SMC wakes up, it calls get_wq_ctx() to

resume the corresponding sleeping thread. But if get_wq_ctx() is

interrupted, goes to sleep and another SMC call is waiting to be allocated

a waitq context, it leads to a deadlock.

To avoid this get_wq_ctx() must be an atomic call and can't be a standard

SMC call. Hence mark get_wq_ctx() as a fast call.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
