CVE-2023-3390: Fixes in Linux Kernel

Published Jun 7, 2023
·
Updated

A flaw in the Linux Kernel found in the Netfilter nftables (net/netfilter/nftablesapi.c). It can lead to use after free vulnerability in nftables when handling sets that are both named and anonymous in batch requests. Nftables allows creating a named set that can be also marked as anonymous by setting the NFTSETANONYMOUS flag. When a rule referencing this malformed set is destroyed, the set gets destroyed as well, as the set is marked anonymous. It is possible to get nftables to destroy the rule, by mangling certain bytes within the rule's bytecode. As this is a named set, the set can be referenced in a different rule at which point it triggers a use after free. The caveat is that all of this needs to be performed in a batch transaction. This is because the reference of any set created in a batch transaction remains in the transactions list even after the set is destroyed.

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1240eb93f0616b21c675416516ff3d74798fdc97

Other sources

A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nftablesapi.c. Mishandled error handling with NFTMSGNEWRULE 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. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97
