To judge from https://github.com/google/oss-fuzz/tree/master/infra/experimental/SystemSan#arbitrary-file-open that new experimental fuzzer isn't documented yet but as far as I can tell it flags "tainted" strings passed to the open syscall. That backtrace points to https://sourceware.org/git/?p=elfutils.git;a=blob;f=libdwfl/dwfl_segment_report_module.c;h=28f87f10dd3962082ec4b995f43069ffc4b5e3d4;hb=HEAD#l784 and I think it's a false positive. Looking at https://github.com/google/oss-fuzz/issues/8497 it seems it should be possible to turn it off eventually. Thanks, Evgeny Vereshchagin
