EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

Memory leak vulnerability in Mali GPU Kernel Driver in Midgard GPU Kernel Driver all versions from r6p0 - r32p0, Bifrost GPU Kernel Driver all versions from r0p0 - r42p0, Valhall GPU Kernel Driver all versions from r19p0 - r42p0, and Avalon GPU Kernel Driver all versions from r41p0 - r42p0 allows a non-privileged user to make valid GPU processing operations that expose sensitive kernel metadata.

Research use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every arm 5th gen gpu architecture kernel driver deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. Fix

    Apply the arm 5th gen gpu architecture kernel driver security patch or hotfix for CVE-2023-26083 on the affected version, following the vendor advisory for your exact build.

  3. Workarounds

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2023-26083 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2023-26083. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

O3 Security · Runtime Protection

Is CVE-2023-26083 being exploited in your environment?

O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2023-26083 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
