Descriptions

In the Linux kernel, the following vulnerability has been resolved:

thermal/debugfs: Free all thermal zone debug memory on zone removal

Because thermal_debug_tz_remove() does not free all memory allocated for
thermal zone diagnostics, some of that memory becomes unreachable after
freeing the thermal zone's struct thermal_debugfs object.

Address this by making thermal_debug_tz_remove() free all of the memory
in question.

Cc :6.8+ <stable@vger.kernel.org> # 6.8+

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Thermal/debugfs: libera toda la memoria de depuración de la zona térmica al eliminar la zona. Debido a que Thermal_debug_tz_remove() no libera toda la memoria asignada para el diagnóstico de la zona térmica, parte de esa memoria se vuelve inalcanzable después de liberar la zona térmica. objeto struct Thermal_debugfs de la zona. Solucione esto haciendo que Thermal_debug_tz_remove() libere toda la memoria en cuestión. CC :6.8+ # 6.8+
