CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of the rockchip-samsung-dcphy PHY register block, where an out-of-range maximum register value can cause attempts to access unmapped memory, leading to system crashes and deadlocks during subsequent PHY operations. This issue primarily impacts systems utilizing the affected PHY hardware, particularly in environments where stability and reliability are critical. Organizations using Linux with this specific PHY configuration should prioritize remediation to prevent potential service disruptions.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: phy: rockchip-samsung-dcphy: fix out-of-range max_register The PHY register block is 64KB, so with a register stride of 4 the last accessible register sits at offset 0xfffc. max_register names 0x10000, one register past the end of the mapping: dumping the registers through the regmap debugfs interface reads beyond the ioremapped region and oopses on the unmapped page. The oops fires with the regmap lock held, so later PHY operations deadlock.
