Last modified
CVE-2022-49421 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: video: fbdev: clcdfb: Fix refcount leak in clcdfb_of_vram_setup of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
