Doc Text:
A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker.

Description Marian Rehak 2022-03-22 07:46:50 UTC 
Uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to uninitialized memory.

Comment 10 Phil Sutter 2022-03-31 17:18:02 UTC 
So, are we z-streaming this fix the usual way into RHEL9.0.0 and older RHEL8? The latter probably until RHEL8.4 since that is what OCP uses?
Comment 11 Justin M. Forbes 2022-03-31 21:27:55 UTC 
This was fixed for Fedora with the 5.16.18 stable kernel updates.
Comment 15 Martin Hecht 2022-09-28 09:28:37 UTC 
will this be addressed in RHEL 8 at some time?
