CVE-2023-52570

CVE-2023-52570 affects the Linux kernel vfio/mdev path. The vulnerability is a NULL pointer dereference that can occur in mdev_unregister_parent() during module removal of the mdpy.mdpy (mdpy.ko), traced to probing/initialization flow (kobject_add_internal/kobject_init_and_add) and mdev_type_add(...

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: 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: vfio: Fix NULL pointer dereference caused by uninitialized group->iommufd

A NULL pointer dereference was found in the VFIO subsystem. When a VFIO group operation fails before group-iommufd is initialized, the cleanup path calls iommufdctxput with a NULL pointer, causing a kernel crash...

kernel: s390/vfio-ap: fix memory leak in vfio_ap device driver

In the s390 VFIO-AP driver, memory allocated for the vfiomatrixdev structure is never released during device cleanup. The release callback incorrectly uses devgetdrvdata to locate the object, but since it was never stored there, the function returns NULL and kfree silently accepts it. The correct...

kernel: vfio: Split migration ops from main device ops

In the Linux kernel, the following vulnerability has been resolved: vfio: Split migration ops from main device ops vfio core checks whether the driver sets some migration op e.g. setstate/getstate and accordingly calls its op. However, currently mlx5 driver sets the above ops without regards to i...

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...
