CVE-2026-98665

Kernel oops via unchecked interrupt scan mask

Published Oct 18, 2026 · Updated Oct 18, 2026

NULL dereference in the Linux max30102 driver allows physically proximate attackers to trigger a kernel oops via device interrupts. The max30102_interrupt_handler function passes active_scan_mask to bitmap_weight before checking interrupt status, although the mask is NULL when the IIO buffer is disabled. The reported trigger involves interrupt-pin wiring on attached hardware with buffering disabled; broader system failure or code execution is not established.
