  3. CVE-2022-50199
In the Linux kernel, the following vulnerability has been resolved: ARM: OMAP2+: Fix refcount leak in omapdss_init_of omapdss_find_dss_of_node() calls of_find_compatible_node() to get device node. of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() in later error path and normal path.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ARM: OMAP2+: Se corrige la fuga de recuento de referencias en omapdss_init_of. Omapdss_find_dss_of_node() llama a of_find_compatible_node() para obtener el nodo del dispositivo. of_find_compatible_node() devuelve un puntero de nodo con el recuento de referencias incrementado; al finalizar, se debe usar of_node_put(). Se añade la falta de of_node_put() en la ruta de error posterior y en la ruta normal.
