CVE-2024-44957
|
| Sažetak |
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. |
