[SRU][F/J/L linux][PATCH 0/1] CVE-2023-34319

[Yuxuan Luo]

[Impact]
Ross Lagerwall discovered that the Xen netback backend driver in the
Linux kernel did not properly handle certain unusual packets from a
paravirtualized network frontend, leading to a buffer overflow. An
attacker in a guest VM could use this to cause a denial of service (host
system crash) or possibly execute arbitrary code.

[Backport]
All clean cherry pick.

[Test]
Compile and boot tested.

[Potential Regression]
Expect low regresssion potential since it has already been backported in
the same way to multiple stable branches.
