Description:
A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault handler. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel.
