Overview

CVE-2026-98093 is a high-severity vulnerability affecting linux linux_kernel. It was published on September 25, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

ASoC: fsl_micfil: balance mclk enable/disable

hw_params() enables mclk unconditionally and hw_free() disables it

unconditionally, but the PCM core does not guarantee 1:1 pairing:

hw_free() can run without hw_params(), and hw_params() can be called

multiple times from the SETUP state. This triggers an "already

disabled" WARN() in the first case and leaks an enable reference in

the second, leaving the clock ungateable.

Guard both sides with the existing mclk_flag, as fsl_sai.c does with

mclk_streams.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
