No remote or adjacent-network packet can reach this code.\nAC:L - There is no race and no dependence on state the attacker cannot influence \u2014 the attacker picks `optlen`, which directly determines the size of the `kmalloc()`\u0027d kernel_optval buffer, so the 96-byte over-read past that object is deterministic and the adjacent slab contents can be groomed by ordinary heap spraying. The one environmental precondition (a cgroup/setsockopt BPF program attached, standard in container/cloud and Android deployments where CONFIG_CGROUP_BPF is on by default) is a vulnerable-configuration property, not a per-attempt condition.\nPR:L - Both entry points check only `ns_capable(sock_net(sk)-\u003euser_ns, CAP_NET_ADMIN)`, which any unprivileged user obtains inside a user+network namespace (`unshare -Urn`); no real root in the initial namespace is needed.\nUI:N - The attacker triggers the out-of-bounds read entirely from their own process by issuing a single short-`optlen` setsockopt call; no victim action is involved.\nS:U - The over-read and its consequences stay inside the kernel\u0027s own memory and the calling task\u0027s network namespace; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 96 bytes (116 for `ebt_replace`) of adjacent kernel slab memory are read past a 1\u201364-byte kmalloc object, and the leaked `tmp.size` then drives a second unbounded `copy_from_sockptr_offset()` of up to `XT_MAX_TABLE_SIZE` (512 MB) from the same object into a table buffer \u2014 far from a strictly bounded few-byte read, exposing arbitrary heap contents including pointers.\nI:N - The defect is purely an out-of-bounds read; the destination of the large follow-on copy is allocated with the same `tmp.size`, so no memory is written out of bounds, and `tmp.counters` is only consumed by `copy_to_user()`, which rejects kernel addresses.\nA:H - The KASAN slab-out-of-bounds report panics hardened/`panic_on_warn` kernels, and on production kernels the heap-garbage-derived `tmp.size` causes a multi-hundred-megabyte `kvmalloc` plus a memcpy that walks off the slab into unmapped direct-map memory, producing an oops/panic and memory exhaustion."

No remote or adjacent-network packet can reach this code.\\nAC:L - There is no race and no dependence on state the attacker cannot influence \\u2014 the attacker picks `optlen`, which directly determines the size of the `kmalloc()`\u0027d kernel_optval buffer, so the 96-byte over-read past that object is deterministic and the adjacent slab contents can be groomed by ordinary heap spraying. The one environmental precondition (a cgroup/setsockopt BPF program attached, standard in container/cloud and Android deployments where CONFIG_CGROUP_BPF is on by default) is a vulnerable-configuration property, not a per-attempt condition.\\nPR:L - Both entry points check only `ns_capable(sock_net(sk)-\u003euser_ns, CAP_NET_ADMIN)`, which any unprivileged user obtains inside a user+network namespace (`unshare -Urn`); no real root in the initial namespace is needed.\\nUI:N - The attacker triggers the out-of-bounds read entirely from their own process by issuing a single short-`optlen` setsockopt call; no victim action is involved.\\nS:U - The over-read and its consequences stay inside the kernel\u0027s own memory and the calling task\u0027s network namespace; no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - Up to 96 bytes (116 for `ebt_replace`) of adjacent kernel slab memory are read past a 1\\u201364-byte kmalloc object, and the leaked `tmp.size` then drives a second unbounded `copy_from_sockptr_offset()` of up to `XT_MAX_TABLE_SIZE` (512 MB) from the same object into a table buffer \\u2014 far from a strictly bounded few-byte read, exposing arbitrary heap contents including pointers.\\nI:N - The defect is purely an out-of-bounds read; the destination of the large follow-on copy is allocated with the same `tmp.size`, so no memory is written out of bounds, and `tmp.counters` is only consumed by `copy_to_user()`, which rejects kernel addresses.\\nA:H - The KASAN slab-out-of-bounds report panics hardened/`panic_on_warn` kernels, and on production kernels the heap-garbage-derived `tmp.size` causes a multi-hundred-megabyte `kvmalloc` plus a memcpy that walks off the slab into unmapped direct-map memory, producing an oops/panic and memory exhaustion.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\":
