# CVE-2024-0607: Kernel: nf_tables: pointer math issue in nft_byteorder_eval()

Status: published. Published: 2024-01-18. Updated: 2026-11-05.

A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.

## Remediation

- workaround: To mitigate this issue, it is possible to prevent the affected code from being loaded by blacklisting the kernel netfilter module.
