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: 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: 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...
