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.

Security readout for executives and security teams

CVE-2007-4571 is an old Linux kernel ALSA information disclosure bug. A local user could cause an ALSA proc interface to return unintended kernel memory contents. The source bundle does not show remote access, privilege escalation, or known active exploitation. Exposure is most likely on legacy Linux systems, appliances, or unsupported embedded builds running kernels before 2.6.22.8 with ALSA enabled and accessible local user accounts. Treat as a legacy hygiene issue unless affected systems still host untrusted local users. It is not a current KEV item, but unsupported kernels with local information disclosure should be removed from production. Mitigation focus: Update to a vendor-supported kernel containing the ALSA fix.; Use vendor advisories from SUSE, Ubuntu, Red Hat, or Debian for distribution-specific packages.; Prioritize unsupported legacy kernels for upgrade or isolation..
