Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked in the top 33% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

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.

finds

Security testing in development can detect unreleased memory, providing partial coverage of the weakness.

prevents

Secure development life cycle mandates memory-management practices that reduce missing-release defects.

prevents

Application security requirements can specify explicit memory-release rules, partially mitigating the weakness.

prevents

Secure system architecture and engineering principles include resource-management guidelines that address memory leaks.

prevents

Secure coding standards directly require proper allocation/deallocation, covering most of this weakness.

finds

Capacity management may detect memory exhaustion symptoms but does not prevent the coding flaw.
