| CVE-2024-27067 | Date: (C)2024-06-19 (M)2024-06-20 |
In the Linux kernel, the following vulnerability has been resolved:
xen/evtchn: avoid WARN() when unbinding an event channel
When unbinding a user event channel, the related handler might be
called a last time in case the kernel was built with
CONFIG_DEBUG_SHIRQ. This might cause a WARN() in the handler.
Avoid that by adding an "unbinding" flag to struct user_event which
will short circuit the handler.
