CVE-2026-43264 at MITRE

Description

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.
