CVE-2023-54035
Description
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fix underflow in chain reference counter
Set element addition error path decrements reference counter on chains
twice: once on element release and again via nft_data_release().
Then, d6b478666ffa ('netfilter: nf_tables: fix underflow in object
reference counter') incorrectly fixed this by removing the stateful
object reference count decrement.
Restore the stateful object decrement as in b91d90368837 ('netfilter:
nf_tables: fix leaking object reference count') and let
nft_data_release() decrement the chain reference counter, so this is
done only once.
