CVE-2022-50157

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A refcount leak issue has been identified in the Linux kernel, specifically in the mc pcie init irq domains() function. The of get next child() function returns a node pointer with an incremented refcount, which should be decremented using of node put() when no longer needed. However, mc pcie init irq domains() only calls of node put() in the normal path, missing it in some error paths, resulting in a refcount leak.

Recommendations To resolve the issue, ensure that of node put() is called in all paths, including error paths, when the node pointer returned by of get next child() is no longer needed. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
