CVE-2026-43060

A flaw was found in the Linux kernel's netfilter (nft_ct) component. When the nft_ct module is removed, packets still enqueued in the nfqueue might retain outdated references to connection tracking (conntrack) zone templates or timeout policies. This can lead to stale references, potentially causing system instability or a denial of service (DoS) if the referenced objects are no longer available.

Red Hat acknowledges the upstream Linux kernel correction for «netfilter» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.
