[PATCH v3 0/5] wifi: rsi: firmware trust boundary hardening

[Tristan Madani]

From: Tristan Madani <tristan@xxxxxxxxxxxxxxxxxxx>

This series adds missing bounds checks for firmware-controlled fields
in the RSI 91x driver (rsi_91x_main.c, rsi_91x_core.c, rsi_91x_mgmt.c).

Each patch addresses a specific field that the firmware can set to an
out-of-range value, causing OOB reads or infinite loops in the host
driver.

Changes in v3:
  - Regenerated from wireless-next with proper git format-patch to
    produce valid index hashes and clean diffs (v2 had post-processed
    index lines that prevented git-am application).

Changes in v2:
  - Clarify firmware trust model in commit messages.

Tristan Madani (5):
  wifi: rsi: fix integer underflow from firmware extended_desc in
    rsi_prepare_skb()
  wifi: rsi: fix OOB read from firmware-claimed length exceeding actual
    frame size
  wifi: rsi: fix OOB read from firmware pad_bytes in management RX path
  wifi: rsi: fix infinite loop when firmware sends zero-length packet
  wifi: rsi: fix OOB read from firmware offset field in SDIO RX path
