CVE-2022-49243 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: atmel: Add missing of_node_put() in at91sam9g20ek_audio_probe This node pointer is returned by of_parse_phandle() with refcount incremented in this function. Calling of_node_put() to avoid the refcount leak.
A memory leak vulnerability has been identified in the Linux kernel's ASoC Atmel audio probe function for the AT91SAM9G20EK. The issue arises because a node pointer returned by 'of_parse_phandle()' lacks a corresponding 'of_node_put()' call, leading to a reference count leak. The vulnerability has been addressed by adding the missing 'of_node_put()' to prevent the refcount leak.
