CVE-2026-68365

Published Aug 10, 2026 EPSS 0.18% (8th pctl)

Overview

CVE-2026-68365 is a known-severity vulnerability. It was published on August 10, 2026.

Technical Description

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

USB: serial: io_edgeport: cap received transmit credits

The interrupt-status packet reports transmit credits returned by the

device. edge_interrupt_callback() adds the 16-bit value to txCredits

without checking maxTxCredits.

edge_write() uses txCredits minus the software FIFO count as the amount

of data that fits. Since the FIFO is allocated with maxTxCredits bytes,

txCredits exceeding maxTxCredits can cause OOB write in ring buffer.

Cap accumulated credits at maxTxCredits. Conforming devices should never

hit the cap.

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.
