  "title": "iio: health: max30102: fix NULL dereference in interrupt handler",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  iio: health: max30102: fix NULL dereference in interrupt handler  The interrupt is requested in max30102_probe() and stays enabled for the lifetime of the device, but indio_dev-\u003Eactive_scan_mask is only valid while a buffer is enabled. When an interrupt arrives while no buffer is enabled, the handler dereferences the NULL active_scan_mask:    Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000   Call trace:    __bitmap_weight\u002B0x64/0x98 (P)    max30102_interrupt_handler\u002B0x48/0x160 [max30102]  Call max30102_fifo_count() at the top of the handler and return early unless it reports a FIFO sample is ready. Because FIFO_RDY is the only interrupt source enabled in max30102_chip_init(), an invocation of max30102_interrupt_handler() without the FIFO_RDY interrupt status bit set carries no data to read and can return before touching active_scan_mask. A negative return from max30102_fifo_count() indicates a failed interrupt status read and is treated the same way.",
