Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: typec: displayport: Fix potential deadlock<br /> <br /> The deadlock can occur due to a recursive lock acquisition of<br /> `cros_typec_altmode_data::mutex`.<br /> The call chain is as follows:<br /> 1. cros_typec_altmode_work() acquires the mutex<br /> 2. typec_altmode_vdm() -&gt; dp_altmode_vdm() -&gt;<br /> 3. typec_altmode_exit() -&gt; cros_typec_altmode_exit()<br /> 4. cros_typec_altmode_exit() attempts to acquire the mutex again<br /> <br /> To prevent this, defer the `typec_altmode_exit()` call by scheduling<br /> it rather than calling it directly from within the mutex-protected<br /> context.
