Apple has issued a security update for iOS that fixes newly discovered kernel and WebKit vulnerabilities that it says have been abused in the wild by attackers.

The kernel vulnerability — CVE-2021-1782 a race condition — allows an attacker to gain privilege escalation, and affects iPhone 6 models and later; iPaid Air 2 and later; iPad mini 4 and later; and the 7th-generation iPad Touch. "Apple is aware of a report that this issue may have been actively exploited," the company said.

The Webkit flaws (CVE-2021-1871 and CVE-2021-1870) allow remote code execution, and affect iPhone 6 models and later; iPad Air 2 and later; iPad mini 4 and later; and the 7th-generation iPad Touch. "Apple is aware of a report that this issue may have been actively exploited," the company said.

The company credited "an anonymous researcher" as reporting each of the flaws, and noted that more details on the flaws will be released. Security researchers, meanwhile, urged iOS users to apply the updates immediately.
