[PATCH 6.6 384/396] scsi: qla2xxx: Fix double free of the ha->vp_map pointer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Saurav Kashyap <skashyap@xxxxxxxxxxx>

commit e288285d47784fdcf7c81be56df7d65c6f10c58b upstream.

Coverity scan reported potential risk of double free of the pointer
ha->vp_map.  ha->vp_map was freed in qla2x00_mem_alloc(), and again freed
in function qla2x00_mem_free(ha).

Assign NULL to vp_map and kfree take care of NULL.
