{"id":"DEBIAN-CVE-2023-53400","details":"In the Linux kernel, the following vulnerability has been resolved:  ALSA: hda: Fix Oops by 9.1 surround channel names  get_line_out_pfx() may trigger an Oops by overflowing the static array with more than 8 channels.  This was reported for MacBookPro 12,1 with Cirrus codec.
