Description

CVE-2025-38249 affecting package kernel for versions less than 6.6.96.1-1

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.
