[SRU][F/J/L][PATCH 0/1] CVE-2023-3772

[Yuxuan Luo]

[Impact]
A flaw was found in the Linux kernel’s IP framework for transforming
packets (XFRM subsystem). This issue may allow a malicious user with
CAP_NET_ADMIN privileges to directly dereference a NULL pointer in
xfrm_update_ae_params(), leading to a possible kernel crash and denial of
service.

[Backport]
Clean cherry picks.
There are two .patch files because the one for Jammy and Lunar cannot be
applied clean on Focal using 'git am'.

[Test]
Compile and boot tested.

[Potential Regression]
Expect minial regression.
