Summary
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):
comm "kworker/u16:2", pid 635322, jiffies 4355801099 (age 1216426.076s)
hex dump (first 32 bytes):
