Linux Kernel Refcount Leak Vulnerability in ARM: OMAP2+ Pdata-quirks

Vulnerability

A refcount leak vulnerability has been identified in the Linux kernel within the ARM: OMAP2+ pdata-quirks component. The issue arises in the pdata_quirks_init_clocks() function, where the loop utilizes of_find_node_by_name() without a corresponding of_node_put() to properly manage the reference count.

Impact

Exploitation of this vulnerability leads to a refcount leak, which can cause memory management issues such as use-after-free vulnerabilities or memory leaks.
