"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nARM: 9484/1: enable interrupts when unhandled user faults are triggered\n\nPREEMPT_RT requires interrupts to be enabled when sending signals.\n\nWhen do_DataAbort()/do_PrefetchAbort() triggers unhandled user faults,\nthat is `inf->fn()` return a non-zero value, and the interrupts are not\nenabled within the hook function, force_sig_fault() will be called\nwith interrupts disabled.\n\nThis can be triggered by user programs executing the bkpt instruction,\nwith kernel config CONFIG_PERF_EVENTS=n.\n\nEnable interrupts in do_DataAbort()/do_PrefetchAbort() when unhandled\nuser faults are triggered to fix the issue."
