Apple has issued a warning to its customers to update their devices as soon as possible.
The tech giant recently released its iOS 15.4.1 update across its iPhones, tablets and desktops, and the patch notes for the update explain that it will fix two zero-day vulnerabilities.
Apple says it is aware 'of a report that [the issues] may have been actively exploited'.
One of the vulnerabilities in question is called CVE-2022-22675, and has been detected across all three platforms.
According to experts, it could allow criminals to perform malicious code with kernel privileges, meaning they could target a device's systems and hardware.
The second issue, CVE-2022-22674, affects macOS and could cause a disclosure of kernel memory – memory used by an operating system.
However, Apple has not expanded on whether or not it had detected instances where these vulnerabilities had been utilised by hackers to access people's devices.
The company stated that the vulnerabilities were actually discovered by 'an anonymous researcher'.
The news comes after customers reported that the recent iOS 15.4 update had caused their batteries to drain more quickly.
This is nothing new, however, as similar issues were also experienced following the rollout of the iOS 14.6, so it wasn't a surprise for a lot of people.
Many customers shared their grievances to social media, claiming they have noticed a stark drop in their battery life, which they put down to the update.
One person said: "iOS 15.4 battery drain is absolutely ridiculous. why can't @[email protected] ever get releases right the first time down 5 percent in less than 10 minutes."

However, Apple assured them that there was nothing to worry about and that devices can take a bit of time to adjust.
Replying to the customer on Twitter, Apple said: "Thanks for reaching out! We'll be happy to help.
