CVE-2012-6703 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Integer overflow in the snd_compr_allocate_buffer function in sound/core/compress_offload.c in the ALSA subsystem in the Linux kernel before 3.6-rc6-next-20120917 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.. EPSS estimates a 0.32% chance of exploitation in the next 30 days.
