| Description | In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack_expect: zero at allocation time
There are occasional LLM hints wrt. leaking uninitialized data to
userspace via ctnetlink. Just zero at allocation time,
expectations are not frequently used these days.
Intentionally keeps _init as-is because we could theoretically
support re-init, so add the missing exp->dir there. |
