CVE-2024-26620

CVE-2024-26620 affects the Linux kernel’s s390 VFIO AP mediated devices (vfio-ap). The issue stems from vfio_ap_mdev_filter_matrix: when a new adapter or domain is assigned to an mdev, only the APID/APQI for the new item was inspected. This could leave AP queues bound to no driver exposed to a gu...

kernel: Linux kernel: Denial of Service in vfio/type1 due to locked_vm underflow

A flaw was found in the Linux kernel's vfio/type1 module. A local user could exploit this vulnerability when a vfio container is preserved across an exec call. If the user unmaps a Direct Memory Access DMA mapping, the lockedvm counter can underflow. This underflow can cause subsequent DMA map...

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...
