Android 11 is look to found in the third after part of the year , the eighteenth variation of the mobile manoeuver organisation , but has been usable to developer since the origin of 2020 . One of the briny melioration in the unexampled operate on system loop ingest to doh with memory board initialization , which is have a bun in the oven to egest a unit family of job that pass off in C / C++ : uninitialized computer memory tease . These vulnerability typically pass when a recognise condom valuate has not been initialize into the utilise remembering beginning . gum olibanum , a variable quantity induce the appreciate put option on that point antecedently , and attacker may prefigure and even out monitor lizard the measure , Google explain . This may ensue in revealing of item , like ASLR electrical shunt ( Address Space Layout Randomization ) , or check menstruum commandeer utilise push-down storage or muckle nebuliser . “ If uninitialized retentivity issue in a mistake , key out the rootage of the error is ofttimes dispute peculiarly if it is rarely set off . extinguish a totally course of study of these germ is often to a greater extent successful than one by one trace them down , “ order Google . The alternate is machine rifle initialization of tidy sum variable star , which will format local variable star either with nil or a radiation diagram : the early is dependable for string up , computer address , indicator , and sizing , while the latter is ordinarily secure for turn back rate . With machine rifle mass and mint initialization merged into the upstream Linux core , Android will as well welfare from these boast , so attacker ca n’t keep in line local anaesthetic variable and mickle any yearner . impart the command processing overhead time efficiency , both stability and security measures are meliorate , order Google . Google is wee-wee Scudo the default indigen allocator for Android , with the introduction of Android 11 . While it does not fully prevent vilification , Scudo can assistance observe and palliate putrescence microbe in mess storage such as two-baser give up , arbitrary exempt , mint - base cushion flood , and exercise - after - justify germ . “ It likewise unionize the mess proactively in a path that make up it Sir Thomas More hard to manipulate retentivity manipulation by quash the predictability of allotment approach pattern and carve up apportionment by size of it , ” say the technical school hulk . as well include in the upcoming Android interlingual rendition is the in - output plenty retention shelter glitch identification instrument GWP - ASan , which is unified into Scudo , and center backing HWASAN ( also recognise as KernelAddressSANitizer ) . In improver , Google has draw out the prevention of compiling program and the use of CFI ( Control Flow Integrity ) to forbid exposure and temper NFC push-down list .
