Detailsinfo

A vulnerability was found in Linux Kernel up to 5.4.210/5.10.136/5.15.60/5.18.17/5.19.1. It has been rated as critical. This issue affects the function omapdss_find_dss_of_node of the component ARM. The manipulation with an unknown input leads to a reference count vulnerability. Using CWE to declare the problem leads to CWE-911. The product uses a reference count to manage a resource, but it does not update or incorrectly updates the reference count. Impacted is availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: ARM: OMAP2+: Fix refcount leak in omapdss_init_of omapdss_find_dss_of_node() calls of_find_compatible_node() to get device node. of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() in later error path and normal path.

The advisory is shared at git.kernel.org. The identification of this vulnerability is CVE-2022-50199 since 06/18/2025. Technical details are known, but no exploit is available.
