Summary
CVE-2023-3390 affecting package kernel for versions less than 5.15.122.1-2
Details

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.
