laforge gerrit-no-reply at lists.osmocom.orglaforge has submitted this change. ( https://gerrit.osmocom.org/c/libusrp/+/25927 ) Change subject: usrp_prims_common: fix use-after-free in get_proto_filename() ...................................................................... usrp_prims_common: fix use-after-free in get_proto_filename() Every time the get_proto_filename() is called, a new instance of std::string is allocated for the first argument. When the function returns, this instance gets deallocated. Therefore, the returned user_filename.c_str() points to free()d memory.
