[SRU][Xenial][PATCH 0/1] CVE-2022-0494

[Yuxuan Luo]

[Impact]
A kernel information leak flaw was identified in the scsi_ioctl function in 
drivers/scsi/scsi_ioctl.c in the Linux kernel due to reading an uninitialized
chunk of memory. This flaw allows a local attacker with a special user privilege
(CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality. 

[Backport]
Since the vulnerability is fixed by adding a flag when allocating the buffer,
all the refactoring commits can be ignored.

[Test]
Compile tested.

[Potential Regression]
Expecting low risk of potential regression which should be limited within the
changed file.
