Overview
CVE-2026-98658 is a known-severity vulnerability. It was published on October 18, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
iio: proximity: aw96103: validate firmware data length
The firmware parser reads a length from the binary header and then uses
it to walk six-byte register/value entries. A truncated firmware image
can make the parser read beyond the copied firmware buffer. A value
smaller than the four-byte count field also underflows, producing a very
large length.
Read the little-endian field with get_unaligned_le32(), as previously
proposed by David Lechner. Validate the header size, reject an
underflowed length, ensure the resulting payload is contained in the
firmware image, and require it to contain whole register/value entries.
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.

How can CyberStrike help with CVE-2026-98658?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-98658 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.
