Description

A flaw was found in the Linux kernel's qixis-fpga driver. This vulnerability is due to incorrect error handling when initializing memory-mapped I/O (Input/Output) regions. An attacker could potentially exploit this flaw by triggering an error condition, which may lead to an invalid pointer dereference. This could result in system instability or a system crash, causing a Denial of Service (DoS).
