{"apiVersion":"1.0","identifier":"CVE-2026-72346","description":"In the Linux kernel, the following vulnerability has been resolved: platform/x86: bitland-mifs-wmi: Fix NULL pointer dereference during suspend/resume The driver registers two distinct WMI devices: a control device (BITLAND_WMI_CONTROL) and an event device (BITLAND_WMI_EVENT). During the probe phase, the event device handling path returns early before initializing the platform profile device (data->pp_dev), leaving it NULL. However, the PM sleep operations are registered globally for the WMI driver and are triggered for both devices. When entering suspend, the event device invokes bitland_mifs_wmi_suspend(), which passes the uninitialized data->pp_dev (NULL) into laptop_profile_get(). This leads to a NULL pointer dereference inside dev_get_drvdata(), causing a kernel Oops and halting the suspend sequence. Fix this by adding a validity check for data->pp_dev in both the suspend and resume callbacks, safely skipping profile operations for the event device.","publishedAt":"2026-08-15T06:22:07","lastModifiedAt":"2026-08-17T06:18:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72346","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00198,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72346","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72346","en":"https://www.redsauce.net/en/cves/CVE-2026-72346","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72346","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72346","de":"https://www.redsauce.net/de/cves/CVE-2026-72346","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72346","el":"https://www.redsauce.net/el/cves/CVE-2026-72346"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72346"}}
