# CVE-2024-44957

> 3.1 LOW

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

xen: privcmd: Switch from mutex to spinlock for irqfds

irqfd_wakeup() gets EPOLLHUP, when it is called by
eventfd_release() by way of wake_up_poll(&ctx->wqh, EPOLLHUP), which
gets called under spin_lock_irqsave(). We can't use a mutex here as it
will lead to a deadlock.

Fix it by switching over to a spin lock.

## Patch verfügbar (OSV)

- Kernel ≥ 6.6.46
- Kernel ≥ 6.10.5
