Description
A flaw was found in the Linux kernel's thermal core subsystem. When thermal_zone_device_register_with_trips() fails during device registration, it does not properly wait for the thermal zone device's removal completion. This can lead to the premature freeing of the device's memory, creating a use-after-free vulnerability. A local attacker could potentially exploit this to cause a denial of service.
