[PATCH] Bluetooth: ISO: fix NULL deref in iso_recv() ISO_END handling

[PATCH] Bluetooth: ISO: fix NULL deref in iso_recv() ISO_END handling

[Nathan Rebello]

The ISO_CONT case in iso_recv() properly checks for unexpected
continuation frames (!conn->rx_len) and oversized fragments
(skb->len > conn->rx_len) before accessing conn->rx_skb. The
ISO_END case lacks both checks.

When an ISO_END packet arrives without a preceding ISO_START:
  - conn->rx_skb is NULL (never allocated)
  - skb_put(conn->rx_skb, ...) dereferences NULL -> kernel crash

When an ISO_END fragment is larger than the remaining expected
length:
  - skb_put() extends past conn->rx_skb->end
  - triggers skb_over_panic -> kernel BUG

KASAN confirmed the NULL-deref on kernel 7.0.0-rc5 via VHCI:

  general protection fault, probably for non-canonical address 0xdffffc0000000018

Fix by adding the same validation that ISO_CONT already has:
reject unexpected end frames and oversized fragments.

[PATCH v2] Bluetooth: ISO: fix NULL deref in iso_recv() ISO_END handling

[Nathan Rebello]

The ISO_CONT case in iso_recv() properly checks for unexpected
continuation frames (!conn->rx_len) and oversized fragments
(skb->len > conn->rx_len) before accessing conn->rx_skb. The
ISO_END case lacks both checks.

When an ISO_END packet arrives without a preceding ISO_START:
  - conn->rx_skb is NULL (never allocated)
  - skb_put(conn->rx_skb, ...) dereferences NULL -> kernel crash

When an ISO_END fragment length does not exactly match the
remaining expected length:
  - the reassembly is malformed and must be rejected

KASAN confirmed the NULL-deref on kernel 7.0.0-rc5 via VHCI:

Changes in v2:
  - Tighten end fragment check from (skb->len > conn->rx_len) to
    (skb->len != conn->rx_len): the end fragment must exactly
    complete the reassembly, not merely avoid overflow.

Changes in v3:
  - Check !conn->rx_skb instead of !conn->rx_len to correctly
    handle the case where an ISO_CONT fragment completes rx_len
    but a valid zero-length ISO_END still follows.

Changes in v2:
  - Tighten end fragment check from (skb->len > conn->rx_len) to
    (skb->len != conn->rx_len): the end fragment must exactly
    complete the reassembly.
