概要
usb: typec: tcpm: fix use-after-free case in tcpm_register_source_caps
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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.
