Overview

CVE-2026-89497 is a high-severity vulnerability. It was published on September 11, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical 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().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
