Title
bpf: Add the missing BPF_LINK_TYPE invocation for sockmap
Summary
In the Linux kernel, the following vulnerability has been resolved: bpf: Add the missing BPF_LINK_TYPE invocation for sockmap There is an out-of-bounds read in bpf_link_show_fdinfo() for the sockmap link fd. Fix it by adding the missing BPF_LINK_TYPE invocation for sockmap link Also add comments for bpf_link_type to prevent missing updates in the future.

There is no network-facing path to bpf_link_show_fdinfo().\nAC:L - Triggering is fully deterministic \u2014 link-\u003etype is unconditionally 14 for every sockmap link, so the out-of-bounds read at index 14 happens on every fdinfo read with no race, timing window, or memory-layout grooming required.\nPR:L - BPF token delegation (kernel 6.9+, present across the affected 6.10\u20136.11 range) routes the CAP_NET_ADMIN/CAP_BPF checks through ns_capable(token-\u003euserns, ...), letting an unprivileged user in a delegated user namespace create the sockmap link; separately, bpf_obj_get() enforces no capability check whatsoever, so any local user able to open a bpffs-pinned sockmap link obtains the fd and reads its own fdinfo.\nUI:N - The attacker performs every step \u2014 creating or opening the link and reading its fdinfo \u2014 within their own process. No victim action or interaction is required.\nS:U - The out-of-bounds read and the resulting disclosure or fault are confined to the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The out-of-bounds qword is dereferenced as a string by seq_printf(\"%s\") with precision -1, so string_nocheck() walks unbounded from an uncontrolled kernel address until a NUL byte and copies those kernel memory bytes into fdinfo output that userspace reads back.\nI:N - The defect is a pure read of one element past a global array; no kernel memory is written out of bounds and no attacker-controlled data modifies kernel state.\nA:H - vsnprintf only guards NULL, sub-PAGE_SIZE, and IS_ERR values, so any other adjacent .data qword becomes a wild kernel dereference and oops, and KASAN globals instrumentation turns the access into a hard report (a panic with panic_on_warn)."
