Description

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

scsi: scsi_dh_alua: Fix memleak for 'qdata' in alua_activate()

If alua_rtpg_queue() failed from alua_activate(), then 'qdata' is not
freed, which will cause following memleak:

unreferenced object 0xffff88810b2c6980 (size 32):
