PPPoE session frames are a link-layer encapsulation and are not routable across L3, so the attacker must be on the same L2 segment (ISP access network of a PPPoE CPE, the router LAN, or a bridged VM/tap network).\\nAC:L - The attacker simply emits a truncated PPPoE session frame carrying fewer than 8 bytes past the Ethernet header \\u2014 there is no race, no memory-layout dependency, and no state the attacker cannot create, since tap/virtio, veth, and L2-tunnel decap paths impose no minimum-frame padding and can be triggered repeatedly at will.\\nPR:N - No credentials or privileges on the target are needed \\u2014 the flowtable ingress hook processes every received frame before any authentication, and the nftables flowtable configuration is the victim admin\u0027s normal router/offload setup, not an attacker prerequisite.\\nUI:N - The out-of-bounds read happens automatically in softirq packet-receive context as soon as the crafted frame arrives on the flowtable-bound interface; no action by any local user or administrator is required.\\nS:U - The out-of-bounds read and its consequences are confined to the kernel\u0027s own memory and the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:L - The bug reads 2 bytes of adjacent kernel heap memory beyond the packet buffer, but the read is strictly bounded to a fixed offset and the value is only compared against PPP_IP/PPP_IPV6, giving at most a weak fast-path-versus-slow-path oracle rather than a general memory-disclosure primitive.\\nI:N - The defect is a read-only over-read; no kernel memory is written, and the misclassified packet\u0027s subsequent handling is re-validated by pskb_may_pull() in nf_flow_tuple_ip() before any header mangling occurs.\\nA:H - The slab-out-of-bounds read is a KASAN-detectable memory-safety violation that panics debug/hardened kernels and can fault when the skb head abuts an unmapped region, and it is triggerable remotely, repeatedly, and without authentication on every arriving frame.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"72efd585f7144a047f7da63864284764596ccad9\", \"lessThan\": \"d06977b9a4109f8738bb276125eb6a0b772bc433\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"72efd585f7144a047f7da63864284764596ccad9\", \"lessThan\": \"8bf7c76a2a207ca2b4cfda0a279192adf27678d7\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"72efd585f7144a047f7da63864284764596ccad9\", \"lessThan\": \"a2471d271042ea18e8a6babc132a8716bb2f08b9\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"72efd585f7144a047f7da63864284764596ccad9\", \"lessThan\": \"cf366ee3bc1b7d1c76a882640ba3b3f8f1039163\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"72efd585f7144a047f7da63864284764596ccad9\", \"lessThan\": \"87b3593bed1868b2d9fe096c01bcdf0ea86cbebf\", \"versionType\": \"git\"}], \"programFiles\": [\"include/net/netfilter/nf_flow_table.h\", \"net/netfilter/nf_flow_table_inet.c\", \"net/netfilter/nf_flow_table_ip.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"5.13\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"5.13\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.15.157\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.88\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.29\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.8.8\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.8.*\"}, {\"status\": \"unaffected\", \"version\": \"6.9\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"include/net/netfilter/nf_flow_table.h\", \"net/netfilter/nf_flow_table_inet.c\", \"net/netfilter/nf_flow_table_ip.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/d06977b9a4109f8738bb276125eb6a0b772bc433\"}, {\"url\": \"https://git.kernel.org/stable/c/8bf7c76a2a207ca2b4cfda0a279192adf27678d7\"}, {\"url\": \"https://git.kernel.org/stable/c/a2471d271042ea18e8a6babc132a8716bb2f08b9\"}, {\"url\": \"https://git.kernel.org/stable/c/cf366ee3bc1b7d1c76a882640ba3b3f8f1039163\"}, {\"url\": \"https://git.kernel.org/stable/c/87b3593bed1868b2d9fe096c01bcdf0ea86cbebf\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnetfilter: flowtable: validate pppoe header\\n\\nEnsure there is sufficient room to access the protocol field of the\\nPPPoe header.
