CVE-2026-89497

EUVD-2026-76403
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().
