This occurs because of an invalid free when the line discipline is used more than once.

GHSA-6794-4VQV-W8QG
Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-09-09 15:34In the Linux kernel, the following vulnerability has been resolved:
netfilter: nat: use kfree_rcu to release ops
Florian Westphal says:
"Historically this is not an issue, even for normal base hooks: the data path doesn't use the original nf_hook_ops that are used to register the callbacks.
However, in v5.14 I added the ability to dump the active netfilter hooks from userspace.
This code will peek back into the nf_hook_ops that are available at the tail of the pointer-array blob used by the datapath.
The nat hooks are special, because they are called indirectly from the central nat dispatcher hook. They are currently invisible to the nfnl hook dump subsystem though.
But once that changes the nat ops structures have to be deferred too."
Update nf_nat_register_fn() to deal with partial exposition of the hooks from error path which can be also an issue for nfnetlink_hook.

Mitigation
Only call matching memory management functions. Do not mix and match routines. For example, when you allocate a buffer with malloc(), dispose of the original pointer with free().
Mitigation
When programming in C++, consider using smart pointers provided by the boost library to help correctly and consistently manage memory.
Mitigation MIT-4.6
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, glibc in Linux provides protection against free of invalid pointers.
Mitigation
Use a language that provides abstractions for memory allocation and deallocation.
No CAPEC attack patterns related to this CWE.
