Compania Google a evaluat utilizarea componentelor \u00een limbajul Rust pe platforma Android. Strategia de implementare a metodelor de dezvoltare sigur\u0103 pentru noul cod \u00een Android s-a dovedit a fi de succes. \u00cen 2025, pentru prima dat\u0103, procentul vulnerabilit\u0103\u021bilor cauzate de erori \u00een gestionarea memoriei a fost mai mic de 20% din totalul vulnerabilit\u0103\u021bilor. Spre compara\u021bie, \u00een 2024 acest indicator \u00een Android era de 24%, iar \u00een 2019 - 76%. \u00cen acela\u0219i timp, media din industrie continu\u0103 s\u0103 r\u0103m\u00e2n\u0103 la nivelul de 70%.

\"Rust<\/center> <\/p>\n

Utilizarea codului scris \u00een Rust pentru dezvoltarea componentelor de sistem Android a \u00eenceput \u00een 2020. \u00cen 2025, volumul de nou cod scris \u00een Rust \u00een Android a dep\u0103\u0219it volumul de cod scris \u00een C \u0219i C++ ad\u0103ugat anual.

\"Rust<\/center> <\/p>\n

Statistica acumulat\u0103 confirm\u0103 presupunerea anterioar\u0103 c\u0103 principala surs\u0103 a problemelor de securitate este noul cod, \u00een timp ce pentru vechiul cod se observ\u0103 o dependen\u021b\u0103 exponen\u021bial\u0103 a securit\u0103\u021bii de timp - cu timpul, erorile din vechiul cod sunt identificate din ce \u00een ce mai rar. \u00cen cele din urm\u0103, Google a decis s\u0103 nu \u00eencerce s\u0103 rescrie vechiul cod \u00een limbaje care gestioneaz\u0103 memoria \u00een mod sigur, ci s\u0103 se concentreze pe utilizarea unor astfel de limbaje pentru noul cod. <\/p>\n

Pe l\u00e2ng\u0103 securitate, implementarea Rust a avut un impact pozitiv asupra vitezei, productivit\u0103\u021bii \u0219i calit\u0103\u021bii dezvolt\u0103rii. Pentru codul pe Rust s-a \u00eenregistrat de 4 ori mai pu\u021bine anul\u0103ri de modific\u0103ri ca urmare a identific\u0103rii erorilor neprev\u0103zute, precum \u0219i o reducere a timpului de revizuire cu 25%.

\"Rust<\/center>
\"Rust<\/center> <\/p>\n

Atunci c\u00e2nd se integreaz\u0103 \u00een Android modific\u0103ri de dimensiuni comparabile, modific\u0103rile scrise \u00een Rust necesit\u0103 cu aproximativ 20% mai pu\u021bine revizii dec\u00e2t omologii lor scri\u0219i \u00een C++.

\"Rust<\/center> <\/p>\n

Aceste date sunt explicate prin simplificarea test\u0103rii \u0219i mutarea identific\u0103rii erorilor \u00een etapele timpurii ale dezvolt\u0103rii, c\u00e2nd erorile devin vizibile \u00eenainte ca dezvoltatorul s\u0103 \u00eenceap\u0103 s\u0103 verifice codul. \u00cen plus, prin eliminarea cheltuielilor indirecte pentru izola\u021bia sandbox \u00een codul pe Rust, s-a reu\u0219it cre\u0219terea performan\u021bei. <\/p>\n

Printre proiectele recente legate de utilizarea Rust pe Android, se eviden\u021biaz\u0103 utilizarea \u00een kernel-ul Linux 6.12 a primului driver pe Rust aplicat pe scar\u0103 larg\u0103, precum \u0219i utilizarea Rust \u00een dezvoltarea firmware-urilor \u0219i aplica\u021biilor. Pe l\u00e2ng\u0103 driverul deja utilizat \u00een kernel scris \u00een Rust, este dezvoltat \u00eempreun\u0103 cu companiile ARM \u0219i Collabora un nou driver GPU \u00een acest limbaj. Protocolul Nearby Presence, implementat \u00een Rust \u0219i folosit \u00een Google Play Services, permite descoperirea dispozitivelor locale prin Bluetooth. O nou\u0103 implementare a protocolului MLS, scris\u0103 \u00een Rust, este planificat\u0103 pentru a fi inclus\u0103 \u00een urm\u0103toarea versiune a aplica\u021biei Google Messages. \u00cen motorul de browser Chromium sunt utilizate parser-e scrise \u00een Rust pentru font-uri web, imagini PNG \u0219i formatul JSON. <\/p>\n

\u00cen prezent, \u00een Android, exist\u0103 aproximativ 5 milioane de linii de cod scrise \u00een Rust, \u00een care a fost identificat\u0103 doar o poten\u021bial\u0103 vulnerabilitate, cauzat\u0103 de probleme legate de gestionarea memoriei. Astfel, densitatea acestor vulnerabilit\u0103\u021bi \u00een codul Rust este de 0.2 vulnerabilit\u0103\u021bi pe milion de linii de cod. Spre compara\u021bie, \u00een codul scris \u00een limbajele C \u0219i C++, acest indicator este de aproximativ 1000 de vulnerabilit\u0103\u021bi pe milion de linii de cod. Sursa principal\u0103 a problemelor \u00een Rust este codul care se afl\u0103 \u00een blocuri unsafe. Propor\u021bia acestui cod este estimat\u0103 la 4% din tot codul scris \u00een Rust. <\/p>\n

Vulnerabilitatea men\u021bionat\u0103 anterior CVE-2025-48530 a fost g\u0103sit\u0103 \u00een biblioteca Crabby Avif, care include un parser \u0219i un decoder pentru formatul Avif. Problema a fost identificat\u0103 de angaja\u021bii Google \u00eenainte de publicarea versiunii \u0219i nu a afectat utilizatorii. Vulnerabilitatea a fost cauzat\u0103 de o eroare \u00een blocul unsafe, ceea ce a dus la un overflow de buffer. Se men\u021bioneaz\u0103 c\u0103, chiar dac\u0103 eroarea nu ar fi fost observat\u0103, exploatarea ei ar fi fost blocat\u0103 de sistemul de distribu\u021bie a memoriei Scudo, care este activat \u00een mod implicit \u00een firmware-uri pentru Google Pixel \u0219i unele alte dispozitive.
