Thu, 14 May 2026 15:22:45 +0200

ALSA: hda: Fix NULL pointer dereference in snd_hda_ctl_add()snd_hda_ctl_add() dereferences kctl->id.subdevice without checkingwhether kctl is NULL. Multiple callers in sound/hda/codecs/ca0132.cpass the return value of snd_ctl_new1() directly to snd_hda_ctl_add()without a NULL check: return snd_hda_ctl_add(codec, nid, snd_ctl_new1(&knew, codec));snd_ctl_new1() returns NULL when the underlying snd_ctl_new() failson memory allocation (kzalloc_flex),which can occur under memorypressure or via fault injection.Add a NULL check at the entry of snd_hda_ctl_add(), matching thepattern already used by snd_ctl_add_replace() at the same callpath (sound/core/control.c:515). Return -EINVAL to let callershandle the error gracefully.Fixes: 44f0c9782cc6 ("ALSA: hda/ca0132: Add tuning controls")Signed-off-by: Quan Sun <2022090917019@std.uestc.edu.cn>Link: https://patch.msgid.link/20260514132245.3062884-1-2022090917019@std.uestc.edu.cnSigned-off-by: Takashi Iwai List of files: /linux/sound/hda/common/codec.c

Thu, 09 Apr 2026 11:38:14 +0200

ALSA: hda: Add sync version of snd_hda_codec_write()We used snd_hda_codec_read() for the verb write when a synchronizationis needed after the write, e.g. for the power state toggle or suchcases. It works in principle, but it looks rather confusing and toohackish.For improving the code readability, introduce a new helper function,snd_hda_codec_write_sync(), which is another variant ofsnd_hda_codec_write(), and replace the existing snd_hda_codec_read()calls with this one.No behavior change but just the code refactoring.Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20260409093826.1317626-2-tiwai@suse.de List of files: /linux/sound/hda/common/codec.c

6692ed9b4ced29aa819c95cc4ad9e2dc8720c081 - ALSA: hda: Notify IEC958 Default PCM switch state changes

Fri, 03 Apr 2026 05:21:34 +0200

ALSA: hda: Notify IEC958 Default PCM switch state changesThe "IEC958 Default PCM Playback Switch" control is backed directly bymout->share_spdif. The share-switch callbacks currently access that statewithout serialization, and spdif_share_sw_put() always returns 0, sonormal userspace writes never emit the standard ALSA control valuenotification.snd_hda_multi_out_analog_open() may also clear mout->share_spdif when theanalog PCM capabilities and the SPDIF capabilities no longer intersect.That fallback is still needed to avoid creating an impossible hwconstraint set, but it changes the mixer backing value without notifyingsubscribers.Protect the share-switch callbacks with spdif_mutex like the other SPDIFcontrol handlers, return the actual change value from spdif_share_sw_put(),and notify the cached control when the open path forcibly disablesshared SPDIF mode after dropping spdif_mutex.This keeps the existing auto-disable behavior while making switch statechanges visible to userspace.Fixes: 9a08160bdbe3 ("[ALSA] hda-codec - Add "IEC958 Default PCM" switch")Fixes: 022b466fc353 ("ALSA: hda - Avoid invalid formats and rates with shared SPDIF")Suggested-by: Takashi Iwai Signed-off-by: Cássio Gabriel Link: https://patch.msgid.link/20260403-hda-spdif-share-notify-v3-1-4eb1356b0f17@gmail.comSigned-off-by: Takashi Iwai List of files: /linux/sound/hda/common/codec.c
