CVE-2024-50028 Information

Description

In the Linux kernel the following vulnerability has been resolved:

thermal: core: Reference count the zone in thermal_zone_get_by_id()

There are places in the thermal netlink code where nothing prevents the thermal zone object from going away while being accessed after it has been returned by thermal_zone_get_by_id().

To address this make thermal_zone_get_by_id() get a reference on the thermal zone device object to be returned with the help of get_device() under thermal_list_lock and adjust all of its callers to this change with the help of the cleanup.h infrastructure.
