CVE-2025-38041 Details
Description
In the Linux kernel, the following vulnerability has been resolved: clk: sunxi-ng: h616: Reparent GPU clock during frequency changes The H616 manual does not state that the GPU PLL supports dynamic frequency configuration, so we must take extra care when changing the frequency. Currently any attempt to do device DVFS on the GPU lead to panfrost various ooops, and GPU hangs. The manual describes the algorithm for changing the PLL frequency, which the CPU PLL notifier code already support, so we reuse that to reparent the GPU clock to GPU1 clock during frequency changes.
A vulnerability in the Linux kernel's handling of GPU clock frequencies for the H616 chipset has been addressed. The issue arose because the H616 manual does not indicate that the GPU Phase-Locked Loop (PLL) can dynamically adjust frequencies. As a result, attempts to implement Dynamic Voltage and Frequency Scaling (DVFS) on the GPU caused errors and hangs in the Panfrost driver. The vulnerability was resolved by reparenting the GPU clock to the GPU1 clock during frequency changes, using an algorithm described in the manual and already supported by the CPU PLL notifier code.
