kernel: Kernel (iommufd): Information Disclosure via uninitialized memory padding

A flaw was found in the kernel. A local attacker could exploit this by triggering a missing zero initialization in the iommufd component when copying vfioiommutype1info to user space. This could lead to the disclosure of sensitive information from uninitialized memory padding...

kernel: iommufd: Check for uptr overflow

A flaw was found in the iommufd subsystem of the Linux kernel. When setting up a mapping with a user virtual address that wraps past zero or otherwise triggers a pointer/size overflow, the kernel may fail to properly validate and constrain the user-provided values. This can result in a buffer...
