CVE-2022-50199 Details
Description
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.
A refcount leak vulnerability has been identified in the Linux kernel's handling of device nodes for the OMAP2+ ARM architecture. The issue arises in the 'omapdss_init_ofomapdss_find_dss_of_node()' function, where 'of_find_compatible_node()' is called to retrieve a device node pointer. This function increments the reference count of the node pointer, but the code fails to decrement the reference count when it is no longer needed, leading to a memory leak. The vulnerability has been addressed by adding the missing 'of_node_put()' call to both the normal and error paths of the function.
