CVE-2026-30656
high
Description
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.
