I don't see any security implication of the fixed bug. Florian, Zack, Alex, do you?

I decrease it to Low.
Based on that incorrect behavior in the nf_tables_updtable can lead to security issue (ex. see older https://access.redhat.com/security/cve/CVE-2023-1095 ), I cannot say if this is not a bug at all.

Thanks, Alex!

Sure, this is undoubtedly a bug. I merely want to reduce the required effort to
deal with it. Is it acceptable to not z-stream CVE fixes if they are low
severity?

A bit off-topic, but CVE-2023-1095 seems fishy, too: The bug is a call to
list_del() for an element not on a list. The respective list_head object has a
defined value though (it was allocated by kzalloc()). The behaviour is
deterministic and immutable AIUI, so not exploitable per se?

Please ignore this question. I just skimmed 27.6. CVE process[1] in RHEL devel
guide which is unambiguous.
