CVE-2024-53682 Details
Description
In the Linux kernel, the following vulnerability has been resolved: regulator: axp20x: AXP717: set ramp_delay AXP717 datasheet says that regulator ramp delay is 15.625 us/step, which is 10mV in our case. Add a AXP_DESC_RANGES_DELAY macro and update AXP_DESC_RANGES macro to expand to AXP_DESC_RANGES_DELAY with ramp_delay = 0 For DCDC4, steps is 100mv Add a AXP_DESC_DELAY macro and update AXP_DESC macro to expand to AXP_DESC_DELAY with ramp_delay = 0 This patch fix crashes when using CPU DVFS.
A vulnerability in the Linux kernel's handling of the AXP717 regulator's ramp delay has been addressed. The issue arose because the AXP717 datasheet specifies a ramp delay of 15.625 microseconds per step, equivalent to 10mV in this context. The vulnerability was related to improper management of the ramp delay, particularly for DCDC4, where the steps should be 100mV. This mismanagement could lead to crashes when using CPU Dynamic Voltage and Frequency Scaling (DVFS). The vulnerability has been resolved by adding specific macros to correctly define and manage the ramp delay, thereby preventing the crashes associated with CPU DVFS.
