{"apiVersion":"1.0","identifier":"CVE-2026-74552","description":"In the Linux kernel, the following vulnerability has been resolved: hwmon: (lm90) Only report alarms if driver is ready Userspace can read sysfs attributes before driver registration is complete, immediately after devm_hwmon_device_register_with_info() has been called. At that time, data->hwmon_dev is not yet initialized. This can trigger a NULL pointer access since lm90_update_device() and with it lm90_update_alarms_locked() will be called. This call schedules report_work and lm90_report_alarms(), which passes the still-NULL data->hwmon_dev to hwmon_notify_event() and triggers a NULL pointer dereference. Fix the problem by only scheduling the report and alert workers data->hwmon_dev is set.","publishedAt":"2026-08-15T13:18:00","lastModifiedAt":"2026-08-19T17:21:10","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74552","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00173,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74552","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74552","en":"https://www.redsauce.net/en/cves/CVE-2026-74552","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74552","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74552","de":"https://www.redsauce.net/de/cves/CVE-2026-74552","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74552","el":"https://www.redsauce.net/el/cves/CVE-2026-74552"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74552"}}
