NewCVE-2022-50575 (opens in a new tab)How to fix?
Upgrade SLES:15.4 kernel-source to version 5.14.21-150400.24.184.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source package as distributed by SLES.
See How to fix? for SLES:15.4 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.
