Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-26083 is a memory leak vulnerability (CWE-401) in the Mali GPU Kernel Driver. It affects Midgard GPU Kernel Driver versions r6p0 through r32p0, Bifrost versions r0p0 through r42p0, Valhall versions r19p0 through r42p0, and Avalon versions r41p0 through r42p0. The flaw permits a non-privileged user to perform valid GPU processing operations that leak sensitive kernel metadata, rated at CVSS 3.3 with local attack vector and low complexity.

A local attacker with a non-privileged account on an affected system can trigger the vulnerability through legitimate GPU operations, resulting in exposure of kernel metadata without requiring elevated privileges or user interaction.

Advisories from Arm and related vulnerability databases, referenced at developer.arm.com and cybersecurity-help.cz, provide further details on affected driver versions and recommended updates. The EPSS score remains low, with a current value of 0.0523 and a peak of 0.0733.
