CVE-2026-89504

Unspecified impact via dangling device-tree pointer

Published Sep 11, 2026 · Updated Sep 11, 2026

Use-after-free in the AS3722 regulator driver in Linux allows attackers to cause unspecified impact via unspecified vectors. as3722_get_regulator_dt_data assigns a referenced child node to pdev->dev.of_node, then prematurely releases that reference and leaves a dangling pointer. Reachability requires an AS3722 regulator device-tree node; the public record identifies neither a subsequent trigger nor a concrete consequence.
