Apple has released a crucial security package aimed at devices that do not support the latest versions of the operating system, aiming to protect users of hardware released in previous years. The measure specifically focuses on fixing vulnerabilities that could allow arbitrary code execution and privacy violations on devices such as the iPhone 11 and specific iPad models. The update arrives to close loopholes that could be exploited by malicious agents, reinforcing the protection of sensitive data.
The installation file is approximately 1.85 GB, varying slightly by device model, and should be downloaded immediately by owners of eligible devices. Para To perform the procedure, the user must access the settings menu, navigate to the general section and select the software update option, ensuring that the device is connected to a Wi-Fi network and has sufficient battery power. The company reinforces that maintaining legacy systems is essential to prevent known flaws from being used in targeted attacks.
Critical kernel and system fixes
Among the most significant changes brought by the new software, the solution to a memory corruption problem in the kernel, identified as CVE-2026-20700, stands out. Esta specific flaw allowed malicious applications to gain root privileges, which in practice would grant full control over the device’s operating system. The fix implemented by Apple engineering improves state management and input validation to neutralize this threat.
Another point of attention resolved involves the privacy mechanism and access to sensitive user data without due permission. Previous Vulnerabilidades allowed certain processes to bypass preferences set by the device owner, exposing contact and location information. With the new build, the permissions logic has been rewritten to ensure that user-imposed restrictions are strictly adhered to by all installed applications.
Vulnerabilities resolved in this release
The released technical documentation details a number of common vulnerability codes and exposures that have been mitigated in this update. The list ranges from flaws in image processing to flaws in wireless communication.
- CVE-2026-20645: Ajuste in state management to fix UI inconsistencies.
- CVE-2026-20674: Reforço in privacy to prevent unauthorized deletion of sensitive data from the system.
- CVE-2026-20650: Correção validation to prevent denial of service via Bluetooth via malformed packets.
- CVE-2026-20638: Solução logic for issues with correctly displaying phone numbers in calls.
- CVE-2026-20660: Bloqueio against arbitrary file writing initiated by remote users.
- CVE-2026-20700: Mitigação of memory corruption that could be exploited in attacks targeting the kernel.
Impact on Bluetooth and connectivity
Users using wireless accessories will notice greater stability and security in Bluetooth connections after installing the update. One of the flaws fixed allowed nearby attackers, within signal range, to cause crashes or service interruptions by sending manipulated data sequences. The update introduces more robust checks on incoming packets, filtering exploitation attempts before they affect device performance.
In addition to security fixes, the update maintains compatibility with existing applications and does not change the visual interface or core functionalities of devices. The focus is purely on the system’s defense infrastructure, ensuring models like the past-generation iPad Air and iPad mini continue to operate securely in an increasingly hostile digital environment.
