CVE-2026-12285
UnknownSummary
Use After Free vulnerability in Arm Ltd GPU kernel drivers (Bifrost, Valhall, Arm 5th Gen) allows a local non-privileged process to access already freed memory via valid GPU memory processing operations.
Risk Assessment
A local attacker could exploit this to escalate privileges or compromise system integrity, potentially leading to full system compromise.
Recommendation
Update Arm GPU kernel drivers to patched versions (e.g., r49p6 or later, r51p1 or later, r54p3 or later) and monitor Arm security advisories.
