CVE-2022-49386 Details
Description
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: am65-cpsw-nuss: Fix some refcount leaks of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. am65_cpsw_init_cpts() and am65_cpsw_nuss_probe() don't release the refcount in error case. Add missing of_node_put() to avoid refcount leak.
A refcount leak vulnerability has been identified in the Linux kernel's AM65 CPSW NUSS Ethernet driver. The issue arises because the function 'of_get_child_by_name()' returns a node pointer with an incremented reference count, which is not properly released in error cases within the 'am65_cpsw_init_cpts()' and 'am65_cpsw_nuss_probe()' functions. This oversight can lead to a memory management issue by leaking reference counts.
