- Summary
- CVE-2025-38249 affecting package kernel for versions less than 6.6.96.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix out-of-bounds read in sndusbgetaudioformatuac3()
In sndusbgetaudioformatuac3(), the length value returned from sndusbctl_msg() is used directly for memory allocation without validation. This length is controlled by the USB device.
The allocated buffer is cast to a uac3clusterheader_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 uac3clusterheader_descriptor.
