Overview

CVE-2024-50268 is a high-severity vulnerability. It was published on November 19, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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: fix potential out of bounds in ucsi_ccg_update_set_new_cam_cmd()

The "*cmd" variable can be controlled by the user via debugfs. That means

"new_cam" can be as high as 255 while the size of the uc->updated[] array

is UCSI_MAX_ALTMODES (30).

The call tree is:

ucsi_cmd() // val comes from simple_attr_write_xsigned()

-> ucsi_send_command()

-> ucsi_send_command_common()

-> ucsi_run_command() // calls ucsi->ops->sync_control()

-> ucsi_ccg_sync_control()

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.
