CVE-2026-79891 is a high-severity flaw (CVSS 8.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
A buffer overflow vulnerability exists in the command line interface of AOS-8 that could allow an unauthenticated remote attacker to run arbitrary commands on the underlying host if certain preconditions outside of the attacker's control are met. Successful exploitation could allow an attacker to execute arbitrary code as a privileged user on the underlying operating system leading to complete system compromise.
Why this priority
- High severity
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
