CVE-2026-98873

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.

EPSS

0.2% chance of exploitation in the next 30 days; higher than 7% of CVEs (scores of 2026-10-25)
