NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default package and not the kernel-default package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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

scsi: qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()

Commit 8c0eb596baa5 ("[SCSI] qla2xxx: Fix a memory leak in an error path of qla2x00_process_els()"), intended to change:

    bsg_job-&gt;request-&gt;msgcode == FC_BSG_HST_ELS_NOLOGIN


bsg_job-&amp;gt;request-&amp;gt;msgcode != FC_BSG_RPT_ELS

but changed it to:

    bsg_job-&gt;request-&gt;msgcode == FC_BSG_RPT_ELS

instead.

Change the == to a != to avoid leaking the fcport structure or freeing unallocated memory.
