The word jailbreak, I believe, is familiar and unfamiliar to Apple users.

Users who have more operational requirements for the device may choose to jailbreak, that is, open the user's operation permissions, obtain the highest permissions of the system, so that they can erase and write the running state of any area at will, and only after the successful jailbreak is the iPhone's file system is in a read-write state. Recently, a hacker on the extranet @b1n4r1b01 announced a potential vulnerability from iOS 15 to iOS 15.1.1, and if this vulnerability is confirmed, it will not take long for us to see the jailbreak of iOS 15 to iOS 15.1.1.
CoolStar hints that semi-jailbreaks for iOS 15 and iPadOS 15 will run without root due to SSV protection, which means that many jailbreak parameters will have to be updated before they can function. The good news is that the Odyssey team's libhooker tuner injection method has made the jailbreak tool support iOS 15 and iPadOS 15.
It is worth mentioning that CoolStar is working on the development of new iOS 15 vulnerabilities, the Checkra1n team is also investigating iOS 15 and iPadOS 15 support through other means, and we may soon see a jailbreak from iOS 15 to iOS 15.1.1 running. Are you looking forward to it?
