CVE-2022-50104 Details
Description
In the Linux kernel, the following vulnerability has been resolved: powerpc/xive: Fix refcount leak in xive_get_max_prio of_find_node_by_path() 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 PowerPC XIVE component. The issue arises in the 'xive_get_max_prio' function, which returns a node pointer with an incremented reference count. Failure to properly decrement this reference count when the pointer is no longer needed leads to a memory management issue. The vulnerability has been addressed by adding the missing 'of_node_put()' function to prevent the refcount leak.
