Apple wrote in the update's CVE entry -- which stands for common vulnerabilities and exposures -- that iOS 17.4.1 addresses two issues that could lead to arbitrary code execution. According to the IT services company Okta, arbitrary code execution could allow a third party to steal your data or hack your device for other nefarious purposes. Apple didn't say these issues were actively exploited, but these issues could be exploited without this update.

According to Apple, both issues were uncovered by Google's Project Zero, a team of security analysts who research and report zero-day vulnerabilities in hardware and software.
