In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
thermal\/drivers\/rcar: Fix error checking in probe()<\/p>\n
This code accidentally calls thermal_zone_device_enable() before checking
\nwhether thermal_zone_device_register_with_trips() failed. Move the call
\nuntil later to avoid an error pointer dereference of “priv->zone”.<\/p>\n
The driver works differently depending on if we are using OF thermal or
\nnot. We use thermal_add_hwmon_sysfs() if we are using OF thermal and
\ncall thermal_zone_device_enable() if not. We can share same error check
\nfor if either of these fail.<\/p>\n
Moving the thermal_zone_device_enable() call is a bit cleaner as well.
\nThe original code used a three step process to cleanup:
\n1. Call thermal_zone_device_unregister() to cleanup.
\n2. Set priv->zone to an error pointer to preserve the error code.
\n3. Set priv->zone to NULL to avoid a second call to
\n thermal_zone_device_unregister() in the rcar_thermal_remove()
\n function.<\/p>\n
Now we can just do a direct goto error_unregister and rcar_thermal_remove()
\nhandles the cleanup properly.<\/p>\n","protected":false},"excerpt":{"rendered":"
