Description

In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix out-of-bounds read in snd_usb_get_audioformat_uac3()
In snd_usb_get_audioformat_uac3(), the length value returned from
snd_usb_ctl_msg() is used directly for memory allocation without
validation. This length is controlled by the USB device.
The allocated buffer is cast to a uac3_cluster_header_descriptor
and its fields are accessed without verifying that the buffer
is large enough. If the device returns a smaller than expected
length, this leads to an out-of-bounds read.
Add a length check to ensure the buffer is large enough for
uac3_cluster_header_descriptor.
