Title
misc: ibmasm: fix OOB MMIO read in ibmasm_handle_mouse_interrupt()
Summary
In the Linux kernel, the following vulnerability has been resolved: misc: ibmasm: fix OOB MMIO read in ibmasm_handle_mouse_interrupt() ibmasm_handle_mouse_interrupt() performs an out-of-bounds MMIO read when the queue reader or writer index from hardware exceeds REMOTE_QUEUE_SIZE (60). A compromised service processor can trigger this by writing an out-of-range value to the reader or writer MMIO register before asserting an interrupt. Since writer is re-read from hardware on every loop iteration, it can also be set to an out-of-range value after the loop has already started. The root cause is that get_queue_reader() and get_queue_writer() return raw readl() values that are passed directly into get_queue_entry(), which computes: queue_begin + reader * sizeof(struct remote_input) with no bounds check. This unchecked MMIO address is then passed to memcpy_fromio(), reading 8 bytes from unintended device registers. For sufficiently large values the address falls outside the PCI BAR mapping entirely, triggering a machine check exception. Fix by checking both indices against REMOTE_QUEUE_SIZE at the top of the loop body, before any call to get_queue_entry(). On an out-of-range value, reset the reader register to 0 via set_queue_reader() before breaking, so that normal queue operation can resume if the corrupted hardware state is transient.

Since writer is re-read from hardware on\\nevery loop iteration, it can also be set to an out-of-range value\\nafter the loop has already started.\\n\\nThe root cause is that get_queue_reader() and get_queue_writer() return\\nraw readl() values that are passed directly into get_queue_entry(),\\nwhich computes:\\n\\n  queue_begin + reader * sizeof(struct remote_input)\\n\\nwith no bounds check. This unchecked MMIO address is then passed to\\nmemcpy_fromio(), reading 8 bytes from unintended device registers.\\nFor sufficiently large values the address falls outside the PCI BAR\\nmapping entirely, triggering a machine check exception.\\n\\nFix by checking both indices against REMOTE_QUEUE_SIZE at the top of\\nthe loop body, before any call to get_queue_entry().
