Noroxi assessment

Priority: Monitor (action score 18/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.50% (FIRST EPSS).
  • No special conditions are required; it is repeatable.
  • Fixed version: linux (Debian:12) 3.14.9-1; linux-2.6 (Debian:6.0) 2.6.32-48squeeze8; kernel (Red Hat:enterprise_linux:6::client) 0:2.6.32-504.8.1.el6.

Low priority for now. Upgrade to linux (Debian:12) 3.14.9-1; linux-2.6 (Debian:6.0) 2.6.32-48squeeze8; kernel (Red Hat:enterprise_linux:6::client) 0:2.6.32-504.8.1.el6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function.
