Overview

CVE-2026-68349 is a known-severity vulnerability. It was published on August 10, 2026.

Technical description

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

wifi: carl9170: fix buffer overflow in rx_stream failover path

The failover continuation in carl9170_rx_stream() copies the full tlen

from the second USB transfer instead of capping at rx_failover_missing

bytes. When both transfers are near maximum size, the total exceeds the

65535-byte failover SKB, triggering skb_over_panic.

Limit the copy size to the missing byte count.

[Fix checkpatch CHECK:PARENTHESIS_ALIGNMENT]

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-2026-68349?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-68349 is actually reachable in your own applications and APIs, then verifies each finding before reporting it.
