CVE-2026-43264

Descrição

In the Linux kernel, the following vulnerability has been resolved: fbdev: of: display_timing: fix refcount leak in of_get_display_timings() of_parse_phandle() returns a device_node with refcount incremented, which is stored in -entry- and then copied to -native_mode-. When the error paths at lines 184 or 192 jump to -entryfail-, native_mode-s refcount is not decremented, causing a refcount leak. Fix this by changing the goto target from -entryfail- to -timingfail-, which properly calls of_node_put(native_mode) before cleanup.
