Title
iommufd: Make sure to zero vfio_iommu_type1_info before copying to user
Summary
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Make sure to zero vfio_iommu_type1_info before copying to user
Missed a zero initialization here. Most of the struct is filled with
a copy_from_user(), however minsz for that copy is smaller than the
actual struct by 8 bytes, thus we don't fill the padding.
Severity ?
No CVSS data available.
