CVE-2026-43414: scsi: qla2xxx: Completely fix fcport double free

Published May 8, 2026
·
Updated

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

scsi: qla2xxx: Completely fix fcport double free

In qla24xxelsdcmdiocb() sp->free is set to qla2x00elsdcmdspfree(). When an error happens, this function is called by qla2x00sprelease(), when krefput() releases the first and the last reference.

qla2x00elsdcmdspfree() frees fcport by calling qla2x00freefcport(). Doing it one more time after krefput() is a bad idea.
