+Subject: ALSA: hda - Enable headset mic on another Dell laptop with ALC3254
+
+From: Chris Chiu <chris.chiu@canonical.com>
+
+commit a5751933a7f6abbdad90d98f25a25bb4b133a9e6 upstream.
+
+There is another Dell Latitude laptop (1028:0c03) with Realtek
+codec ALC3254 which needs the ALC269_FIXUP_DELL4_MIC_NO_PRESENCE
+instead of the default matched ALC269_FIXUP_DELL1_MIC_NO_PRESENCE.
+Apply correct fixup for this particular model to enable headset mic.

+Subject: ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF
+
+From: Clement Lecigne <clecigne@google.com>
+
+[ Note: this is a fix that works around the bug equivalently as the
+ two upstream commits:
+ 1fa4445f9adf ("ALSA: control - introduce snd_ctl_notify_one() helper")
+ 56b88b50565c ("ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF")
+ but in a simpler way to fit with older stable trees -- tiwai ]
+
+Add missing locking in ctl_elem_read_user/ctl_elem_write_user which can be
+easily triggered and turned into an use-after-free.
+
+Example code paths with SNDRV_CTL_IOCTL_ELEM_READ:
+
+64-bits:
+snd_ctl_ioctl
+ snd_ctl_elem_read_user
+ [takes controls_rwsem]
+ snd_ctl_elem_read [lock properly held, all good]
+ [drops controls_rwsem]
+
+32-bits (compat):
+snd_ctl_ioctl_compat
+ snd_ctl_elem_write_read_compat
+ ctl_elem_write_read
+ snd_ctl_elem_read [missing lock, not good]
+
+CVE-2023-0266 was assigned for this issue.
