However, event\ndetection is not supported for all sensors, and if userspace tries to\nconfigure accelerometer wakeup events on a sensor device that does not\nsupport them (e.g. LSM6DS0), st_lsm6dsx_write_event() dereferences a NULL\npointer when trying to write to the wakeup register.\nDefine an additional struct iio_chan_spec array whose members have a NULL\nevent_spec field, and use this array instead of st_lsm6dsx_acc_channels for\nsensors without event detection capability.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/33c683417232b9111e29458954529942137780a3","https://git.kernel.org/stable/c/4d60ffcdedfe2cdb68a1cde19bb292bc67451629","https://git.kernel.org/stable/c/7673167fac9323110973a3300637adba7d45de3a","https://git.kernel.org/stable/c/81ed6e42d6e555dd978c9dd5e3f7c20cb121221b","https://git.kernel.org/stable/c/c34e2e2d67b3bb8d5a6d09b0d6dac845cdd13fb3"],"products":[],"source":"nvd","synced_at":"2026-10-30T13:47:47.119061695+00:00"},"epss":{"cve":"CVE-2025-71198","score":0.00197,"percentile":0.09418,"date":"2026-10-30"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
