How to fix?

There is no fixed version for RHEL:8 kernel-headers.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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

xen/privcmd: Fix a possible warning in privcmd_ioctl_mmap_resource()

As 'kdata.num' is user-controlled data, if user tries to allocate memory larger than(>=) MAX_ORDER, then kcalloc() will fail, it creates a stack trace and messes up dmesg with a warning.

Call trace: -> privcmd_ioctl --> privcmd_ioctl_mmap_resource

Add __GFP_NOWARN in order to avoid too large allocation warning. This is detected by static analysis using smatch.
