Apple Releases Urgent iPhone and iPad Updates to Patch New Zero-Day Vulnerability

Apple on Monday introduced a safety update for iOS and iPad to tackle a essential vulnerability that it suggests is remaining exploited in the wild, earning it the 17th zero-day flaw the firm has tackled in its items due to the fact the commence of the year.’

The weakness, assigned the identifier CVE-2021-30883, issues a memory corruption issue in the “IOMobileFrameBuffer” component that could permit an application to execute arbitrary code with kernel privileges. Crediting an anonymous researcher for reporting the vulnerability, Apple stated it is “knowledgeable of a report that this issue might have been actively exploited.”

Complex particulars about the flaw and the character of the assaults stay unavailable as yet, as is the identity of the danger actor, so as to make it possible for a majority of the buyers to implement the patch and avert other adversaries from weaponizing the vulnerability. The Iphone maker reported it dealt with the problem with improved memory handling.

Safety researcher Saar Amar shared more particulars, and a evidence-of-concept (PoC) exploit, noting that “this attack surface is extremely intriguing for the reason that it really is available from the application sandbox (so it’s great for jailbreaks) and several other processes, making it a very good candidate for LPEs exploits in chains.”

CVE-2021-30883 is also the next zero-working day impacting IOMobileFrameBuffer following Apple tackled a comparable, anonymously documented memory corruption concern (CVE-2021-30807) in July 2021, raising the probability that the two flaws could be linked. With the newest repair, the organization has settled a history 17 zero-times to day in 2021 by itself —
