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().
A flaw was found in the Linux kernel's Orange File System (orangefs) client. The orangefs_prepare_cdm_array() function incorrectly calculates the buffer size for client debug keywords when an entry starts with a space. This can lead to a buffer overflow, allowing data to be written beyond the intended memory boundary. Such memory corruption could potentially result in a denial of service or other unspecified impacts.
