Summary
In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpm: fix double-free issue in tcpm_port_unregister_pd() When unregister pd capabilitie in tcpm, KASAN will capture below double -free issue. The root cause is the same capabilitiy will be kfreed twice, the first time is kfreed by pd_capabilities_release() and the second time is explicitly kfreed by tcpm_port_unregister_pd().
