Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 6.14.1. Affected is the function nfqnl_build_packet_message. The manipulation with an unknown input leads to a initialization vulnerability. CWE is classifying the issue as CWE-665. The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlink_queue: Initialize ctx to avoid memory allocation error It is possible that ctx in nfqnl_build_packet_message() could be used before it is properly initialize, which is only initialized by nfqnl_get_sk_secctx(). This patch corrects this problem by initializing the lsmctx to a safe value when it is declared. This is similar to the commit 35fcac7a7c25 ("audit: Initialize lsmctx to avoid memory allocation error").

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2025-22110 since 12/29/2024. There are known technical details, but no exploit is available.
