AI-suggested
A fix is available that switches the Tegra SoC thermal driver to use devm_thermal_of_cooling_device_register(), ensuring proper unregistration of cooling devices during driver removal. Users should update to a Linux kernel version that includes this fix.
Description
A vulnerability in the Linux kernel's Tegra SoC thermal driver was resolved by switching to devm cooling device registration. Previously, the driver removal function did not unregister cooling devices, leaving references to freed memory, which could cause stability issues. The fix ensures proper unregistration of cooling devices during driver removal, preventing use-after-free conditions.
