Summary

[none]

Details

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