When an interrupt arrives while no\nbuffer is enabled, the handler dereferences the NULL active_scan_mask:\n\n  Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000\n  Call trace:\n   __bitmap_weight+0x64/0x98 (P)\n   max30102_interrupt_handler+0x48/0x160 [max30102]\n\nCall max30102_fifo_count() at the top of the handler and return early\nunless it reports a FIFO sample is ready. Because FIFO_RDY is the only\ninterrupt source enabled in max30102_chip_init(), an invocation of\nmax30102_interrupt_handler() without the FIFO_RDY interrupt status bit\nset carries no data to read and can return before touching\nactive_scan_mask. A negative return from max30102_fifo_count()\nindicates a failed interrupt status read and is treated the same way.","state":0,"publishedAt":"2026-10-18T15:44:35.323+00:00","modifiedAt":"2026-10-21T12:55:30.413+00:00","affected":[{"ecosystem":"Vendor
