ALSA: wavefront: Fix integer overflow in sample size validation

2025-12-18T12:55:23+00:00

commit 0c4a13ba88594fd4a27292853e736c6b4349823d upstream. The wavefront_send_sample() function has an integer overflow issue when validating sample size. The header->size field is u32 but gets cast to int for comparison with dev->freemem Fix by using unsigned comparison to avoid integer overflow.

ALSA: ad1816a: Fix potential NULL pointer deref in snd_card_ad1816a_pnp()

2025-07-17T16:37:09+00:00

commit 043faef334a1f3d96ae88e1b7618bfa2b4946388 upstream. Use pr_warn() instead of dev_warn() when 'pdev' is NULL to avoid a potential NULL pointer dereference.

ALSA: sb: Force to disable DMAs once when DMA mode is changed

2025-07-10T14:05:06+00:00

[ Upstream commit 4c267ae2ef349639b4d9ebf00dd28586a82fdbe6 ] When the DMA mode is changed on the (still real!) SB AWE32 after playing a stream and closing, the previous DMA setup was still silently kept, and it can confuse the hardware, resulting in the unexpected noises. As a workaround, enforce the disablement of DMA setups when the DMA setup is changed by the kcontrol. https://bugzilla.kernel.org/show_bug.cgi?id=218185 Link: https://patch.msgid.link/20250610064322.26787-2-tiwai@suse.de Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin

ALSA: sb: Don't allow changing the DMA mode during operations

2025-07-10T14:05:06+00:00

[ Upstream commit ed29e073ba93f2d52832804cabdd831d5d357d33 ] When a PCM stream is already running, one shouldn't change the DMA mode via kcontrol, which may screw up the hardware. Return -EBUSY instead.

ALSA: wss: Use standard print API
