Noroxi assessment

Priority: Monitor (action score 8/100)

  • 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: 0.40% (FIRST EPSS).
  • No special conditions are required; it is repeatable.
  • Fixed version: kernel-source (openSUSE:Tumbleweed) 4.8.13-1.1; kernel (Red Hat:enterprise_linux:6::client) 0:2.6.32-71.14.1.el6; kernel-debug (Red Hat:enterprise_linux:6::client) 0:2.6.32-71.14.1.el6.

Low priority for now. Upgrade to kernel-source (openSUSE:Tumbleweed) 4.8.13-1.1; kernel (Red Hat:enterprise_linux:6::client) 0:2.6.32-71.14.1.el6; kernel-debug (Red Hat:enterprise_linux:6::client) 0:2.6.32-71.14.1.el6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The hso_get_count function in drivers/net/usb/hso.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.
