Vulnerability from github – Published: 2024-07-12 15:31 – Updated: 2025-11-04 00:30

Details

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.

Severity ?

7.8 (High)
