+Subject: ALSA: emu8000: Fix a use after free in snd_emu8000_create_mixer
+
+From: Lv Yunlong <lyl2019@mail.ustc.edu.cn>
+
+commit 1c98f574403dbcf2eb832d5535a10d967333ef2d upstream.
+
+Our code analyzer reported a uaf.
+
+In snd_emu8000_create_mixer, the callee snd_ctl_add(..,emu->controls[i])
+calls snd_ctl_add_replace(.., kcontrol,..). Inside snd_ctl_add_replace(),
+if error happens, kcontrol will be freed by snd_ctl_free_one(kcontrol).
+Then emu->controls[i] points to a freed memory, and the execution comes
+to __error branch of snd_emu8000_create_mixer. The freed emu->controls[i]
+is used in snd_ctl_remove(card, emu->controls[i]).
+
+My patch set emu->controls[i] to NULL if snd_ctl_add() failed to avoid
+the uaf.

+Subject: ALSA: hda/conexant: Re-order CX5066 quirk table entries
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 2e6a731296be9d356fdccee9fb6ae345dad96438 upstream.
+
+Just re-order the cx5066_fixups[] entries for HP devices for avoiding

+No functional changes.
+
+Also Cc-to-stable for the further patch applications.

+Subject: ALSA: sb: Fix two use after free in snd_sb_qsound_build
+
+From: Lv Yunlong <lyl2019@mail.ustc.edu.cn>
+
+commit 4fb44dd2c1dda18606348acdfdb97e8759dde9df upstream.
+
+In snd_sb_qsound_build, snd_ctl_add(..,p->qsound_switch...) and
+snd_ctl_add(..,p->qsound_space..) are called. But the second
+arguments of snd_ctl_add() could be freed via snd_ctl_add_replace()
+->snd_ctl_free_one(). After the error code is returned,
+snd_sb_qsound_destroy(p) is called in __error branch.
+
+But in snd_sb_qsound_destroy(), the freed p->qsound_switch and
+p->qsound_space are still used by snd_ctl_remove().
+
+My patch set p->qsound_switch and p->qsound_space to NULL if
+snd_ctl_add() failed to avoid the uaf bugs. But these codes need
+to further be improved with the code style.

+Subject: ALSA: usb-audio: Add dB range mapping for Sennheiser Communications Headset PC 8
+
+From: Timo Gurr <timo.gurr@gmail.com>
+
+commit ab2165e2e6ed17345ffa8ee88ca764e8788ebcd7 upstream.
+
+The decibel volume range contains a negative maximum value resulting in
+pipewire complaining about the device and effectivly having no sound
+output. The wrong values also resulted in the headset sounding muted
+already at a mixer level of about ~25%.

+Subject: ALSA: usb-audio: Explicitly set up the clock selector
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit d2e8f641257d0d3af6e45d6ac2d6f9d56b8ea964 upstream.
+
+In the current code, we have some assumption that the audio clock
+selector has been set up implicitly and don't want to touch it unless
+it's really needed for the fallback autoclock setup.  This works for
+most devices but some seem having a problem.  Partially this was
+covered for the devices with a single connector at the initialization
+phase (commit 086b957cc17f "ALSA: usb-audio: Skip the clock selector
+inquiry for single connections"), but also there are cases where the
+wrong clock set up is kept silently.  The latter seems to be the cause
+of the noises on Behringer devices.
+
+In this patch, we explicitly set up the audio clock selector whenever
+the appropriate node is found.
