The nft\_verdict\_init() function allows positive values as drop error within the hook verdict, and hence the nf\_hook\_slow() function can cause a double free vulnerability when NF\_DROP is issued with a drop error which resembles NF\_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. Official description from the CVE record, published by Google. Copyright © 1999-2026 The MITRE Corporation.
