Description

A flaw was found in fio (Flexible I/O Tester). A local user could exploit this vulnerability by providing a specially crafted job file that includes the fdp_pli option without an argument. This leads to a NULL pointer dereference, which occurs when the program attempts to access a memory location that has not been assigned, resulting in a segmentation fault and a Denial of Service (DoS) due to a process crash.
