Description

A flaw was found in the Linux kernel's Intel GVT-g (Graphics Virtualization Technology) debugfs component. When a device is removed through unbinding, the intel_gvt_debugfs_clean() function may attempt to access a debugfs root that has already been deallocated, leading to a NULL pointer dereference. A local attacker could exploit this vulnerability to cause a kernel crash, resulting in a Denial of Service (DoS).
