In the Linux kernel, the following vulnerability has been resolved: ARM: 9484/1: enable interrupts when unhandled user faults are triggered PREEMPT_RT requires interrupts to be enabled when sending signals. When do_DataAbort()/do_PrefetchAbort() triggers unhandled user faults, that is `inf->fn()` return a non-zero value, and the interrupts are not enabled within the hook function, force_sig_fault() will be called with interrupts disabled. This can be triggered by user programs executing the bkpt instruction, with kernel config CONFIG_PERF_EVENTS=n. Enable interrupts in do_DataAbort()/do_PrefetchAbort() when unhandled user faults are triggered to fix the issue.
