CVE-2026-68355

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

Overview

CVE-2026-68355 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: ath11k: fix potential buffer underflow in ath11k_hal_rx_msdu_list_get()

When the first entry in msdu_details has a zero buffer address,

the code accesses msdu_details[i - 1] with i == 0, causing a

buffer underflow.

Fix similarly to ath12k_wifi7_hal_rx_msdu_list_get() by adding

a separate check for i == 0 before the main condition to prevent

the out-of-bounds access.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
