[SRU][J/L/M][PATCH 0/1] CVE-2023-5158

[Yuxuan Luo]

[Impact]
A flaw was found in vringh_kiov_advance in drivers/vhost/vringh.c in the
host side of a virtio ring in the Linux Kernel. This issue may result in
a denial of service from guest to host via zero length descriptor.

[Backport]
It is a clean cherry pick.

[Test]
Compile and boot tested.

[Potential Regression]
Expect low regression potential that's limited to vhost users.
