CVE-2025-0050: Mali GPU Userspace Driver allows an Out-of-Bounds access
Noroxi assessment
Priority: Monitor (action score 23/100)
- 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: 0.16% (FIRST EPSS).
- Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Arm Ltd Arm 5th Gen GPU Architecture Userspace Driver r49p3, r54p0; Arm Ltd Bifrost GPU Userspace Driver r49p3; Arm Ltd Valhall GPU Userspace Driver r49p3, r54p0.
Low priority for now. Upgrade to Arm Ltd Arm 5th Gen GPU Architecture Userspace Driver r49p3, r54p0; Arm Ltd Bifrost GPU Userspace Driver r49p3; Arm Ltd Valhall GPU Userspace Driver r49p3, r54p0 or later.
