Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from the fact that iommuattachdevicepasid initializes handle-dev only after iommusvalock is released. As a result, the handle bound with the device may return a NULL pointer for the dev pointer. This allows iommusvaunbinddevi...
