Apple has released Safari 15.6.1 to fix a zero-day vulnerability that is tracked as CVE-2022-32893 and exploited in the wild by attackers.
Apple said the bug had been fixed through improved bounds checking.
While Apple patched the same zero-day vulnerability yesterday for macOS Monterey and iPhone/iPads, the recently released update for Safari will help fix the vulnerability in macOS Big Sur and Catalina.
The vulnerability is an out-of-bounds write issue in Webkit that allows an attacker to remotely execute code on a vulnerable device.
An out-of-bounds write vulnerability allows attackers supply input to a program that causes it to write data over the end or before the start of the memory buffer, with various adverse effects, including program crashes, data corruption, or in the worst case, remote code execution.
“Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited,” Apple warns.
