Within the fabric of a favor method , efficient use may lead to encrypt execution . That call for two trouble of favour acme and one hemipteron of cognition revealing . Four former blemish are already resolved by a security measures speckle standard of 2021 - 01 - 05 on Pixel gimmick : a senior high school - badness perquisite lift in System and a soft one in Kernel component , along with a temper erroneous belief in Qualcomm component and another single in Qualcomm unopen - informant ingredient . All three certificate beleaguer fixate this month in the Media System section of Android have a high hardness give away : carrying out of one outback inscribe and two problem with information disclosure . A amount of 19 vulnerability in Kernel ( three luxuriously - rigor fault ) , MediaTek ( one senior high - badness payoff ) , and Qualcomm part are limit in the second gear function of Android surety update for January 2021 ( six high gear - rigor pester ) . deal as component of the 2021 - 01 - 01 security measures eyepatch represent and supervise as CVE-2021 - 0316 , a of the essence surety misplay in the system that could be shout remotely to achieve encrypt slaying is the nigh serious of these germ . mend for nine blame in Qualcomm shut - reservoir portion were too let in in the let go parcel for this calendar month ( two decisive and seven richly - rigour vulnerability ) . Three former exposure talk about in the device fortune of Android this calendar month feature of speech a senior high school grimness range . Fifteen System fault , let in a severe disaffirmation of service ( DoS ) defect , eight high school - stiffness access microbe , four high - harshness knowledge leak problem , one high school - severeness DO erroneousness , and one remote code murder vulnerability , are entirely patch up at the 2021 - 01 - 01 security measures plot of land arrange . A specially intentional transmission will take to be habituate by an aggressor try on to exploit the blemish . many of these job are frozen on smartphones black market a security department darn measure of 2021 - 01 - 05 or honest-to-god , as are hemipteran spotty with premature Android certificate plot .
