Overview

CVE-2026-97560 is a known-severity vulnerability. It was published on September 25, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix one-byte OOB read in smb2_parse_native_symlink()

When parsing a share-root relative native symlink, memcpy copies

smb_target+1 (skipping the leading separator) but uses

strlen(smb_target)+1 as the length, reading one byte past the

allocated buffer.

This fixes the following KASAN splat when accessing an SMB symlink

with a target of '\a\b':

How can CyberStrike help with CVE-2026-97560?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-97560 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
