Vulnerable software:
Linux kernel
Software vendor:

Description

The vulnerability allows a local user to gain access to sensitive information.

The snd_mem_proc_read function in sound/core/memalloc.c in the Advanced Linux Sound Architecture (ALSA) in the Linux kernel before 2.6.22.8 does not return the correct write size, which allows local users to obtain sensitive information (kernel memory contents) via a small count argument, as demonstrated by multiple reads of /proc/driver/snd-page-alloc.


Remediation

Install update from vendor's website.
