BELL-CVE-2026-92515

Affected: Alpaquita:25: linux-lts, Alpaquita:stream: linux-lts

fkie_cve-2026-92515

In the Linux kernel, the following vulnerability has been resolved:

bpf: Preserve unique-field state across nested structs

btf_find_struct_field() initializes a fresh seen mask for every recursive descent. Unique special fields in different levels of the same aggregate therefore do not see one another. The duplicate fields can reach btf_parse_fields(), where they trigger an invariant WARN_ON_ONCE(). A crafted user BTF can consequently trigger the warning before map creation checks capabilities.

Initialize the seen mask once in btf_find_field() and pass the same pointer through struct, datasec, and nested-struct walks. This gives the entire field traversal one shared uniqueness state.
