CVE-2007-4571

17
FAUCET Score

CVE-2007-4571 describes an information disclosure vulnerability in the Advanced Linux Sound Architecture (ALSA) within the Linux kernel, specifically affecting versions prior to 2.6.22.8. A flaw in the snd_mem_proc_read function allows local users to read sensitive kernel memory contents by repeatedly querying /proc/driver/snd-page-alloc with a small count argument. This vulnerability has a low severity CVSS score of 2.1, indicating a local attack vector with low complexity and a potential impact of only confidentiality compromise (C:P). There is no integrity or availability impact. While not actively exploited in the wild or on hot lists, a proof-of-concept exploit (EDB-30605) exists on ExploitDB. There is no evidence of Metasploit or Nuclei modules, and community discussion and media coverage are minimal.
