In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_conntrack: destroy stale expectfn expectations on unregister NAT… (CVE-2026-53349)CVE-2026-53349 0 A vulnerability in the Linux kernel's netfilter nf_conntrack subsystem could cause a use-after-free condition when NAT helpers unregister while expectations still exist. This occurs because stale pointers to module code remain in the expectation table after module removal, leading to kernel crashes when those pointers are dereferenced. The issue requires CAP_SYS_MODULE privileges to exploit and is considered a robustness flaw rather than a direct attack vector.
