Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iommufd: Make sure to zero vfioiommutype1info before copying it to the user. A zero initialization was missed here. Most of the struct is filled using a copyfromuser function; however, the minsz parameter for that copy is 8 bytes...

CVE-2023-54034

The CVE-2023-54034 issue affects the Linux kernel iommufd path where vfio_iommu_type1_info is copied to user space. The root cause is a missing zero initialization: most of the struct is copied with copy_from_user(), but minsz is smaller than the struct by 8 bytes, leaving the padding uninitializ...
