Description Dhananjay Arunesh 2020-08-12 03:06:47 UTC

Stack-based buffer overflow in the supply_lm_input_write function in drivers/thermal/supply_lm_core.c in the MSM Thermal driver for the Linux kernel, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted application that sends a large amount of data through the debugfs interface.
