GCVE-110-AUR-2026-001805

The Arch User Repository (AUR) package `viennacl` was identified as malicious during the June 2026 AUR supply-chain compromise, in which an attacker pushed backdoored PKGBUILDs to roughly 1,900 packages. Building or installing the affected package executed attacker-controlled code. The malicious revision has since been removed from the AUR. Upstream package description: "The library provides high level C++ interfaces for linear algebra routines on CPUs and GPUs using CUDA, OpenCL and OpenMP.".
