Linux Kernel Security Advisory: Copy Fail & Dirty Frag

Recently disclosed Linux kernel vulnerabilities known as Copy Fail (CVE‑2026‑31431) and Dirty Frag (CVE‑2026‑43284, CVE‑2026‑43500) affect many Linux distributions released since 2017, including CentOS, Ubuntu, Debian, AlmaLinux, and Rocky Linux. These may impact the operating system running on your SolVPS virtual private server (VPS).

What you should know

• These are local privilege escalation vulnerabilities
• An attacker would need existing access to the system
• On an unpatched VPS, a compromised process could gain root‑level access
• Linux vendors have released updates or mitigations for these issues

To protect our platform and other customers, VPS servers found to be actively compromised may be temporarily suspended until the issue is resolved.

Platform and customer responsibilities

SolVPS infrastructure is currently being reviewed and updated as part of our ongoing security maintenance efforts.
At the same time, the operating system inside your VPS is customer‑managed, including applying kernel and security updates.

Your options

Option 1: Migrate to a new VPS (Recommended)

• Provision a new VPS with the latest OS and security updates
• Migrate your data and cancel your existing VPS
• One month of VPS charges for the new server will be waived

Migration assistance is available through our Professional Services team for an additional fee.
To proceed, open a support ticket and request: “New VPS for Copy Fail and Dirty Frag mitigation.”

Option 2: Secure your existing VPS

• Update your kernel and reboot (recommended), or
• Apply vendor‑provided temporary mitigations if updates are not immediately possible

Temporary mitigations are not a permanent fix and will still require a kernel update later.

SolVPS will not be responsible for any issues arising from a customer’s failure to update or patch as recommended above.

Vendor advisories

We recommend reviewing guidance from your Linux distribution:

• Ubuntu, Debian, AlmaLinux, and Rocky Linux advisories are available via their official security channels.
