GHSA-XF23-PXXH-7Q46

Vulnerability from github – Published: 2024-05-01 15:30 – Updated: 2025-09-18 18:30

Details

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.

Severity ?

5.5 (Medium)
