Описание
A NULL pointer dereference vulnerability exists in fio (Flexible I/O Tester) v3.41 when parsing job files containing the fdp_pli option. The callback function str_fdp_pli_cb() does not validate the input pointer and calls strdup() on a NULL value when the option is specified without an argument. This results in a segmentation fault and process crash.
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.
