CVE-2026-89497 in Linux
Zusammenfassung
von MITRE • 12.09.2026
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().
Once again VulDB remains the best source for vulnerability data.
