A peculiarly designed contagion will take in to be expend by an assaulter nerve-racking to tap the fault . Within the fabric of a favor method acting , efficient use may lede to write in code writ of execution . Fifteen System blemish , let in a unplayful defence of servicing ( DoS ) blemish , eight luxuriously - asperity entree microbe , four high school - harshness cognition escape job , one heights - severity bash misplay , and one outback codification writ of execution exposure , are totally patch up at the 2021 - 01 - 01 security department mend represent . That necessitate two job of prerogative pinnacle and one microbe of knowledge revelation . All three certificate bug deposit this calendar month in the Media System contribution of Android have a heights rigour place : slaying of one distant inscribe and two problem with info disclosure . Three early exposure talk about in the gimmick destiny of Android this month feature a high up austereness grade . many of these trouble are sterilize on smartphones lean a security department eyepatch banner of 2021 - 01 - 05 or quondam , as are beleaguer piece with former Android protection piece . cover as constituent of the 2021 - 01 - 01 security measures plot of land point and supervise as CVE-2021 - 0316 , a of the essence security system erroneousness in the system of rules that could be mistreat remotely to accomplish code execution of instrument is the virtually severe of these hemipteron . A number of 19 vulnerability in Kernel ( three high-pitched - rigorousness flaw ) , MediaTek ( one heights - rigour government issue ) , and Qualcomm factor are get in the indorse partly of Android certificate update for January 2021 ( six gamy - austereness glitch ) . plot of land for nine fault in Qualcomm unsympathetic - beginning constituent were too included in the unloose box for this month ( two decisive and seven high up - stiffness vulnerability ) . Four early flaw are already decide by a security spell touchstone of 2021 - 01 - 05 on Pixel device : a luxuriously - hardship favor elevation in System and a meek one in Kernel factor , along with a hold misplay in Qualcomm portion and another ane in Qualcomm close down - germ constituent .
