CVE-2024-40903

Disclosure Date: July 12, 2024
Add MITRE ATT&CK tactics and techniques that apply to this CVE.

Description

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

usb: typec: tcpm: fix use-after-free case in tcpm_register_source_caps

There could be a potential use-after-free case in
tcpm_register_source_caps(). This could happen when:

  • new (say invalid) source caps are advertised
  • the existing source caps are unregistered
  • tcpm_register_source_caps() returns with an error as
    usb_power_delivery_register_capabilities() fails

This causes port->partner_source_caps to hold on to the now freed source
caps.

Reset port->partner_source_caps value to NULL after unregistering
existing source caps.
