CVE-2026-89721

A flaw was found in the Linux kernel's phy: rockchip-samsung-dcphy component. A local attacker with access to the regmap debugfs interface could trigger an out-of-bounds read by attempting to dump registers. This occurs because the maxregister value is incorrectly set, causing the system to read...
