CVE-2022-49438 Details
Description
In the Linux kernel, the following vulnerability has been resolved: Input: sparcspkr - fix refcount leak in bbc_beep_probe of_find_node_by_path() calls of_find_node_opts_by_path(), which returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
A refcount leak vulnerability has been identified in the Linux kernel's handling of the sparcspkr input. The issue arises in the bbc_beep_probe function, which calls of_find_node_opts_by_path(). This function returns a node pointer with an incremented reference count, but the refcount is not properly decremented after use, leading to a memory leak. The vulnerability has been addressed by adding the missing of_node_put() call to release the reference and prevent the leak.
