Description
A flaw was found in the Linux kernel's hibernate functionality for arm64 architectures. When the system attempts to save memory tags during hibernation, a failure in this process can prevent the proper restoration of the Disable Asynchronous Interrupts and Fast interrupts (DAIF) state. This leaves the system in an unexpected state with interrupts masked, which may lead to system instability or unresponsiveness.
