Summary
scsi: qla2xxx: Fix improper freeing of purex item
Details

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

scsi: qla2xxx: Fix improper freeing of purex item

In qla2xxxprocesspurlsiocb(), an item is allocated via qla27xxcopymultiplepkt(), which internally calls qla24xxallocpurex_item().

The qla24xxallocpurex_item() function may return a pre-allocated item from a per-adapter pool for small allocations, instead of dynamically allocating memory with kzalloc().

An error handling path in qla2xxxprocesspurls_iocb() incorrectly uses kfree() to release the item. If the item was from the pre-allocated pool, calling kfree() on it is a bug that can lead to memory corruption.

Fix this by using the correct deallocation function, qla24xxfreepurex_item(), which properly handles both dynamically allocated and pre-allocated items.
