[SRU][Jammy-OEM-5.17/OEM-6.0][PATCH 0/1] CVE-2023-3390

[Yuxuan Luo]

[Impact]
A use-after-free vulnerability was found in the Linux kernel's netfilter
subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with
NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same
transaction causing a use-after-free vulnerability. This flaw allows a local
attacker with user access to cause a privilege escalation issue. 

[Backport]
It is a clean cherry pick.

[Test]
Compile and boot tested.

[Potential Regression]
Expect low regression potential.
