"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nARM: 9481/2: breakpoint: CFI breakpoints only on demand\n\nThis removes the stub hw_breakpoint_cfi_handler() from ARM, making\nit not steal breakpoint type 0x03 (ARM_ENTRY_CFI_BREAKPOINT) unless\nCFI is actively used in the kernel.\n\nWhen not instrumenting with CFI, or when a breakpoint is issued in\nuserspace, we fall through to return 1 from hw_breakpoint_pending()\n\"unhandled fault\" so userspace can make use of this breakpoint.\n\nTested with LKDTM and this command line:\necho CFI_FORWARD_PROTO > /sys/kernel/debug/provoke-crash/DIRECT\nstill works as expected."
