The vulnerability (CVE-2026-93063) in the Linux kernel's iwlwifi mei component involved a missing verification of the SAP message length before reading the message data. Without this check, a buffer overflow could occur if the SAP message size was larger than the allocated buffer, potentially leading to arbitrary code execution or system compromise. The issue has been resolved by implementing a length check to validate the SAP message size prior to processing.

Successful exploitation could allow an attacker with local access to cause a buffer overflow, resulting in high impact including confidentiality, integrity, and availability compromise of the affected system. The CVSS v3.1 score is 8.4, reflecting high severity with local attack vector, low attack complexity, no privileges required, and no user interaction needed.

A fix has been applied to the Linux kernel to verify the SAP message length before reading it, preventing buffer overflow. Users should update to the patched kernel version containing this fix. Since this is not a cloud service, remediation depends on applying the official kernel update. Patch status is confirmed by the advisory stating the vulnerability has been resolved.
