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

scsi: qla2xxx: Fix memory leak in qla2x00_probe_one()

There is a memory leak reported by kmemleak:

unreferenced object 0xffffc900003f0000 (size 12288):
comm "modprobe", pid 19117, jiffies 4299751452 (age 42490.264s)
hex dump (first 32 bytes):
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
backtrace:
[<00000000629261a8>] __vmalloc_node_range+0xe56/0x1110
[<0000000001906886>] __vmalloc_node+0xbd/0x150
[<000000005bb4dc34>] vmalloc+0x25/0x30
[<00000000a2dc1194>] qla2x00_create_host+0x7a0/0xe30 [qla2xxx]

[<00000000641ccc04>] local_pci_probe+0xeb/0x1a0

The root cause is traced to an error-handling path in qla2x00_probe_one()
when the adapter "base_vha" initialize failed. The fab_scan_rp "scan.l" is
used to record the port information and it is allocated in
qla2x00_create_host(). However, it is not released in the error handling
path "probe_failed".

Fix this by freeing the memory of "scan.l" when an error occurs in the
adapter initialization process.
