CVE-2025-40278

CVE-2025-40278 affects the Linux kernel net: sched: act_ife code path. The issue stems from a partially initialized tc_ife structure in tcf_ife_dump(), where a designated initializer left padding uninitialized and nla_put() copies the whole struct to userspace, exposing kernel memory. The advisor...
