CVE-2026-53081

The CVE-2026-53081 issue affects the Linux kernel BPF verifier: when two scalar registers carry BPF_ADD_CONST, id mapping could become inconsistent because the compound id (base | ADD_CONST) was mapped without validating the underlying base IDs. This could allow two verifier states where one deri...
