CVE-2026-46021

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> thermal: core: Fix thermal zone governor cleanup issues<br /> <br /> If thermal_zone_device_register_with_trips() fails after adding<br /> a thermal governor to the thermal zone being registered, the<br /> governor is not removed from it as appropriate which may lead to<br /> a memory leak.<br /> <br /> In turn, thermal_zone_device_unregister() calls thermal_set_governor()<br /> without acquiring the thermal zone lock beforehand which may race with<br /> a governor update via sysfs and may lead to a use-after-free in that<br /> case.<br /> <br /> Address these issues by adding two thermal_set_governor() calls, one to<br /> thermal_release() to remove the governor from the given thermal zone,<br /> and one to the thermal zone registration error path to cover failures<br /> preceding the thermal zone device registration.
