Estado: AnalizadaMedia (5.5)—

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

ARM: OMAP2+: omap4-common: Fix refcount leak bug

In omap4_sram_init(), of_find_compatible_node() will return a node pointer with refcount incremented. We should use of_node_put() when it is not used anymore.
