CVE-2022-49241 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: atmel: Fix error handling in sam9x5_wm8731_driver_probe The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This function only calls of_node_put() in the regular path. And it will cause refcount leak in error path.
A refcount leak vulnerability has been identified in the Linux kernel's ASoC Atmel WM8731 driver. The issue arises in the 'sam9x5_wm8731_driver_probe' function, where the device_node pointer, returned by 'of_parse_phandle()' with an incremented refcount, is not properly released using 'of_node_put()' in the error handling path. This oversight can lead to a memory leak by failing to decrement the reference count when the function encounters an error.
