The vulnerability allows an attacker to bypass the intended network filtering protections, potentially leading to unauthorized network access, data leakage, or disruption of services. The weakness is a classic example of a misconfigured privilege boundary within the kernel, classified under CWE-284.", "risk_and_exploitability": "The CVSS score of 7.3 indicates high severity. However, the EPSS score is below 1%, showing a low current exploitation probability. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires compromising the kernel or gaining privileged access, after which the attacker can effectively disable nftables. While the risk to the confidentiality, integrity, or availability of the network is significant, the low exploitability reduces the urgency compared to high EPSS threats."}}}}, "created": "2026-03-06T15:08:03.806516+00:00", "updated": "2026-04-16T12:45:35.841800+00:00", "vendors": ["suse", "suse$PRODUCT$suse_linux_enterprise_server"]}
