AI-suggested
A patch is available and should be applied. The vulnerability is fixed in Linux kernel versions 5.15.0-1092.99~20.04.1 and later as listed in the established facts. Users should update to these fixed kernel versions to remediate the issue. No additional mitigation actions are required beyond applying the official kernel updates.
Description
CVE-2025-38332 is a vulnerability in the Linux kernel's SCSI lpfc driver where the BIOS version string handling uses strlcat() with FORTIFY support, causing a kernel panic due to perceived buffer overflow. The issue is fixed by replacing the strlcat() usage with memcpy() and ensuring proper null termination. This flaw affects multiple Linux kernel versions prior to fixed releases and can cause denial of service via kernel panic.
