Description

The snd_compress_check_input function in sound/core/compress_offload.c in the ALSA subsystem in the Linux kernel before 3.17 does not properly check for an integer overflow, which allows local users to cause a denial of service (insufficient memory allocation) or possibly have unspecified other impact via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl call.

Affected products

• Debian Linux: 8.0
• Linux kernel: from 3.7 before 3.12.62; from 3.13 before 3.16.37 — fixed in 3.12.62, 3.16.37
• Novell Suse Linux Enterprise Real Time Extension: 12-sp1

How to fix

Upgrade to a fixed version: Linux kernel 3.12.62, 3.16.37. Check the vendor advisory for mitigations.
