Libinput teegib teavet, mis pakub \u00fchtekuuluvat sisendiviidi virna Waylandi ja X.Org Serveri jaoks, avastas haavatavuse (CVE-d ei ole m\u00e4\u00e4ratud), mis v\u00f5imaldab kohaliku kasutaja poolt root \u00f5igustega koodi t\u00e4itmist, kui on \u00fchendatud virtuaalne sisendiseade, mis on simuleeritud kasutajasf\u00e4\u00e4ris l\u00e4bi uinput v\u00f5i uhid.

Haavatavus esineb udev-k\u00e4sitlejas libinput-device-group ja
\ntekib seoses n\u00f5uetekohase eraldamise puudumisega spetsiaalsete m\u00e4rkide osas atribuutides, mis saadakse seadmetelt ja edastatakse udev alams\u00fcsteemi kujul «v\u00f5ti=v\u00e4\u00e4rtus».

Tavaliselt on uinput ja uhid juurdep\u00e4\u00e4s saadaval ainult root kasutajale, kuid m\u00f5nedes distributsioonides on tarnitud udev reeglid, mis v\u00f5imaldavad privileegideta kasutajatel kasutada uinput'i.
