ALSA: asihpi: Fix potential OOB array access at reading cache

2026-06-01T15:39:34+00:00

commit 7b7d6572145c1dab2dd9bfb550b188e5f0ff3c3f upstream. find_control() to retrieve a cached info accesses the array with the given index blindly, which may lead to an OOB array access. Add a sanity check for avoiding it.

ALSA: ua101: Reject too-short USB descriptors

2026-06-01T15:39:34+00:00

commit b59d5c51bb328a60749b4dd5fe7e649bfb4089b4 upstream. find_format_descriptor() walks the class-specific interface extras by advancing with bLength. It rejects descriptors that extend past the remaining buffer, but it does not reject descriptor lengths smaller than a USB descriptor header. Reject too-short descriptors before using bLength to advance the local scan. This keeps the UA-101 parser robust against malformed descriptor data and matches the usual USB descriptor walking rules.

ALSA: usb-audio: Bound MIDI endpoint descriptor scans

2026-06-01T15:39:32+00:00

commit d6854daa67be623860f4e1873fd3d3c275aba4ed upstream. snd_usbmidi_get_ms_info() validates the internal MIDIStreaming endpoint descriptor size before using baAssocJackID[], but the descriptor walker can still return a class-specific endpoint descriptor whose bLength exceeds the remaining bytes in the endpoint-extra scan. That leaves later flexible-array reads bounded by bLength, but not by the remaining bytes in the endpoint-extra scan. Stop walking when bLength is zero or extends past the remaining endpoint-extra scan.

ASoC: SOF: stream-ipc: Check for cstream nullity in sof_ipc_msg_data()

2026-06-01T15:39:31+00:00

[ Upstream commit d8d99c3b5c485f339864aeaa29f76269cc0ea975 ] The nullity of sps->cstream should be checked similarly as it is done in sof_set_stream_data_offset() function. Assuming that it is not NULL if sps->stream is NULL is incorrect and can lead to NULL pointer dereference.

ASoC: SOF: pcm: Clear the susbstream pointer to NULL on close

2026-06-01T15:39:31+00:00

[ Upstream commit 46c7b901e2a03536df5a3cb40b3b26e2be505df6 ] The spcm->stream[substream->stream].substream is set during open and was left untouched. After the first PCM stream it will never be NULL and we have code which checks for substream NULLity as indication if the stream is active or not. For the compressed cstream pointer the same has been done, this change will correct the handling of PCM streams.

ALSA: core: Serialize deferred fasync state checks

2026-06-01T15:39:31+00:00

[ Upstream commit 5337213381df578058e2e41da93cbd0e4639935f ] snd_fasync_helper() updates fasync->on under snd_fasync_lock, and snd_fasync_work_fn() now also evaluates fasync->on under the same lock. snd_kill_fasync() still tests the flag before taking the lock, leaving an unsynchronized read against FASYNC enable/disable updates. Move the enabled-state check into the locked section. Also clear fasync->on under snd_fasync_lock in snd_fasync_free() before unlinking the pending entry. Together with the locked sender-side check, this publishes teardown before flushing the deferred work and prevents a racing sender from requeueing the entry after free has started.

ALSA: hda/conexant: Fix missing error check for jack detection

2026-06-01T15:39:29+00:00

[ Upstream commit b0e2333a231107adedd38c6fcfe1adc6162716fc ] In cx_probe(), the return value of snd_hda_jack_detect_enable_callback() is ignored. This function returns a pointer, and if it fails (e.g., due to memory allocation failure), it returns an error pointer which must be checked using IS_ERR(). If the registration fails, the driver continues to probe, but the jack detection callback will not be registered. This can lead to a kernel crash later when the driver attempts to handle jack events or accesses the uninitialized structure. Check the return value using IS_ERR() and propagate the error via PTR_ERR() to the probe caller.
