Overview

CVE-2024-35790 is a medium-severity vulnerability. It was published on May 17, 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:

usb: typec: altmodes/displayport: create sysfs nodes as driver's default device attribute group

The DisplayPort driver's sysfs nodes may be present to the userspace before

typec_altmode_set_drvdata() completes in dp_altmode_probe. This means that

a sysfs read can trigger a NULL pointer error by deferencing dp->hpd in

hpd_show or dp->lock in pin_assignment_show, as dev_get_drvdata() returns

NULL in those cases.

Remove manual sysfs node creation in favor of adding attribute group as

default for devices bound to the driver. The ATTRIBUTE_GROUPS() macro is

not used here otherwise the path to the sysfs nodes is no longer compliant

with the ABI.

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.
