CVE-2022-49676 Details
Description
In the Linux kernel, the following vulnerability has been resolved: memory: samsung: exynos5422-dmc: Fix refcount leak in of_get_dram_timings of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. This function doesn't call of_node_put() in some error paths. To unify the structure, Add put_node label and goto it on errors.
A refcount leak vulnerability has been identified in the Linux kernel's memory management for Samsung Exynos5422. The issue arises in the 'of_get_dram_timings_of_parse_phandle()' function, which returns a node pointer with an incremented reference count. The vulnerability occurs because the function fails to decrement the reference count in certain error paths, leading to a memory leak. The vulnerability has been addressed by adding a 'put_node' label to properly manage the reference count and unify the error handling structure.
