GCVE-110-AUR-2026-000917

The Arch User Repository (AUR) package `linux-cachyos-rc-native-headers` 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: "Headers and scripts for building modules for the Linux BORE + LTO + AutoFDO + Propeller + Cachy Sauce Kernel by CachyOS with other patches and improvements - Release Candidate kernel".
