Description Thomas Leroy 2023-06-29 08:41:25 UTC

CVE-2023-3390

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.

Fixing commit:
1240eb93f0616b21c675416516ff3d74798fdc97

Commit introducing the bug:
958bee14d071 ("netfilter: nf_tables: use new transaction infrastructure to handle sets")

Comment 1 Thomas Leroy 2023-06-29 08:42:28 UTC

Buggy commit is on the following branches:
- SLE15-SP4
- cve/linux-4.12
- cve/linux-4.4
- cve/linux-5.3
- stable              (already has the fix)

Comment 4 Michal Kubeček 2023-07-20 16:32:57 UTC

It's a similar headache as bsc#120295 - and for similar reasons. 5.14 and
5.3 based branches are submitted but there is no chance to apply the logic
of the fix to 4.12 or older without (at the very least)

  bb7b40aecbf7  netfilter: nf_tables: bogus EBUSY in chain deletions
  cd5125d8f518  netfilter: nf_tables: split set destruction in deactivate
                and destroy phase
  f6ac85858976  netfilter: nf_tables: unbind set in rule from commit path

which, apart from being quite intrusive, break kABI.

Simply speaking, the idea of the fix is to split the call of
nft_rule_expr_deactivate() hidden in nf_tables_rule_release() out of it so
that it can be called with a different phase parameter. But we do not have
the notion of deactivate in 4.12 at all - or the phases.

At the moment it's not really obvious if 4.12 code is actually affected
(by this CVE as described, that is, it is certainly affected by other issues
which were the reason for introducing the missing code) and if it is, if it
can be fixed without backporting all the infrastructure introduced in
mainline between 4.12 and 5.3.

Michal, do you think we can discard 4.12 and 5.3 as affected, or are you still thinking in a way to backport the fix to them? Thanks!
