How to fix?

There is no fixed version for Centos:10 kernel-zfcpdump-modules.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules package and not the kernel-zfcpdump-modules package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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

iommufd/viommu: Release the igroup lock on the vdevice_size error path

iommufd_vdevice_alloc_ioctl() takes idev->igroup->lock, then validates the driver's vdevice_size against the core structure size with a WARN_ON_ONCE. On failure that guard jumps to out_put_idev, below out_unlock_igroup, so it skips the mutex_unlock(), leaving the igroup lock held and deadlocking the next vDEVICE operation on that group.

Jump to out_unlock_igroup instead.
