"value": "AV:N - The damaging consequence is reached through the IPsec ESP receive path — a remote peer's ESP packets drive `esp_input()`, whose completion callback `esp_input_done` → `xfrm_input_resume()` is invoked by the stm32-cryp threaded IRQ handler with BH enabled. The upstream engine check that this driver violates was itself added after the same failure was hit with network traffic (iperf over IPsec).\nAC:L - The BH-enabled completion happens on every interrupt-mode request, and the recursion requires only that a NET_RX softirq land on the same CPU while `x->lock` is held — a window the attacker widens at will by sustaining ESP packet volume, controlling both sides of the race. The original reporter reproduced it with ordinary iperf load.\nPR:N - No credentials on the target are needed: ESP frames sent to a known SPI enter `esp_input()` and reach `esp_input_done` even when authentication fails, and ordinary tunnel traffic from any remote host suffices. The alternate local vector via AF_ALG is likewise available to a fully unprivileged user.\nUI:N - Triggering requires only sending network traffic to a device whose IPsec/crypto operations are backed by the STM32 CRYP accelerator; no action by any local user or administrator is involved.\nS:U - The fault is a locking-context violation contained entirely within the kernel; no VM, IOMMU, or sandbox boundary is crossed and no other security authority is affected.\nC:N - The defect is an incorrect execution context for a completion callback, not a memory-safety error — there is no out-of-bounds read, no freed-object reuse, and no path by which attacker-readable data is exposed.\nI:N - No memory is corrupted and no attacker-controlled write primitive arises; the callback simply runs with bottom halves enabled, which affects serialization rather than data content.\nA:H - Recursive acquisition of `xfrm_state->lock` from the re-entered `xfrm_input()` produces a spinlock-recursion BUG and a hard deadlock on that CPU, hanging IPsec/network processing (and panicking outright under `panic_on_warn`)."
