Description
In the Linux kernel, the following vulnerability has been resolved: orangefs: skip leading spaces before parsing client debug masks orangefs_prepare_cdm_array() sizes each client debug keyword buffer with strcspn(cds_head, " "), but then parses the keyword with %s. The %s conversion skips leading whitespace, while strcspn() does not. If a client debug entry starts with a space, the allocation can be sized for an empty keyword while sscanf() copies the following non-empty token. This can write past the end of the allocated keyword buffer. Skip leading spaces before computing the keyword length so the allocation matches the string parsed by sscanf().
