In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix double free of the ha->vp_map pointer
Coverity scan reported potential risk of double free of the pointer ha->vpmap. ha->vpmap was freed in qla2x00memalloc(), and again freed in function qla2x00memfree(ha).
Assign NULL to vp_map and kfree take care of NULL.
