2 months agomedia: vidtv: fix NULL pointer dereference in vidtv_channel_pmt_match_sections

media: vidtv: fix NULL pointer dereference in vidtv_channel_pmt_match_sections

syzbot reported a general protection fault in vidtv_psi_desc_assign [1].

vidtv_psi_pmt_stream_init() can return NULL on memory allocation
failure, but vidtv_channel_pmt_match_sections() does not check for
this. When tail is NULL, the subsequent call to
vidtv_psi_desc_assign(&tail->descriptor, desc) dereferences a NULL
pointer offset, causing a general protection fault.

Add a NULL check after vidtv_psi_pmt_stream_init(). On failure, clean
up the already-allocated stream chain and return.

2 months agomedia: vidtv: fix nfeeds state corruption on start_streaming failure
Ruslan Valiyev [Sun, 1 Mar 2026 21:07:35 +0000 (21:07 +0000)] 
media: vidtv: fix nfeeds state corruption on start_streaming failure

syzbot reported a memory leak in vidtv_psi_service_desc_init [1].

When vidtv_start_streaming() fails inside vidtv_start_feed(), the
nfeeds counter is left incremented even though no feed was actually
started. This corrupts the driver state: subsequent start_feed calls
see nfeeds > 1 and skip starting the mux, while stop_feed calls
eventually try to stop a non-existent stream.

This state corruption can also lead to memory leaks, since the mux
and channel resources may be partially allocated during a failed
start_streaming but never cleaned up, as the stop path finds
dvb->streaming == false and returns early.

Fix by decrementing nfeeds back when start_streaming fails, keeping
the counter in sync with the actual number of active feeds.

While only vidtv_ts_null_write_into() has triggered a report so far,

standby_cancel() to the end of start_streaming(), after all mode,
crop, and timing registers have been configured. Also explicitly stop
master mode (XMSTA=1) when stopping the stream, matching the pattern

Use IMX283_STANDBY (bit 0) instead of IMX283_STBLOGIC (bit 1) when
stopping streaming. STBLOGIC only puts the sensor logic into standby but
leaves the MIPI interface (along with other components) in an
indeterminate state.

This (presumably) causes the CSI receiver (e.g. Raspberry Pi's CFE) to
miss the LP-11 to HS transition when streaming restarts, resulting in a
hang of 10+ seconds. The issue is most visible when immediately
restarting a full-resolution stream after stopping a 3x3 binned one, so
that runtime suspend hasn't yet been triggered.

Writing IMX283_STANDBY puts the entire sensor into standby. The
imx283_standby_cancel() sequence already handles the full wakeup from
this suspended state.

call instead dmaengine_terminate_async (aka without synchronize) and call
again right after a new dmaengine_submit to setup again a new transfer.

Pull debugobjects fix from Thomas Gleixner:
 "A single fix for debugobjects.

  The deferred page initialization prevents debug objects from
  allocating slab pages until the initialization is complete. That
  causes depletion of the pool and disabling of debugobjects.

  The reason is that debugobjects uses __GFP_HIGH for allocations as it
  might be invoked from arbitrary contexts. When PREEMPT_COUNT is
  disabled there is no way to know whether the context is safe to set
  __GFP_KSWAPD_RECLAIM.

  This worked until v6.18. Since then allocations w/o a reclaim flag
  cause new_slab() to end up in alloc_frozen_pages_nolock_noprof(),
  which returns early when deferred page initialization has not yet
  completed.

  Work around that when PREEMPT_COUNT is enabled as the preempt counter
  allows debugobjects to add __GFP_KSWAPD_RECLAIM to the GFP flags when
  the context is preemtible. When PREEMPT_COUNT is disabled the context
  is unknown and the reclaim bit can't be set because the caller might
  hold locks which might deadlock in the allocator.

  That makes debugobjects depend on PREEMPT_COUNT ||
  !DEFERRED_STRUCT_PAGE_INIT, which limits the coverage slightly, but
  keeps it functional for most cases"
