CVE-2025-38285

Local service interruption via nested BPF tracepoints

Published Jul 10, 2025 · Updated Jul 14, 2026

Reachable assertion in the Linux kernel allows local users to interrupt service by executing nested BPF raw-tracepoint stack helpers. get_bpf_raw_tp_regs applies WARN_ON_ONCE when a tracepoint such as trace_mmap_lock_acquire_returned recursively invokes the raw-tracepoint stack path. Exploitation requires local BPF program execution; Siemens embeds the affected kernel in the additional GNU/Linux subsystem of the listed controllers.
