CVE-2024-27067 xen/evtchn: avoid WARN() when unbinding an event channel

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 CONFIGDEBUGSHIRQ. This might cause a WARN in the handle...

CVE-2024-27067

The CVE-2024-27067 issue is in the Linux kernel (xen/evtchn) where unbinding a user event channel could cause a WARN() in the handler if the kernel is built with CONFIG_DEBUG_SHIRQ. The fix adds an "unbinding" flag to struct user_event to short-circuit the handler, preventing the WARN() when unbi...
