  3. CVE-2022-49984
In the Linux kernel, the following vulnerability has been resolved: HID: steam: Prevent NULL pointer dereference in steam_{recv,send}_report It is possible for a malicious device to forgo submitting a Feature Report. The HID Steam driver presently makes no prevision for this and de-references the 'struct hid_report' pointer obtained from the HID devices without first checking its validity. Let's change that.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: HID: Steam: Impedir la desreferencia de puntero nulo en steam_{recv,send}_report. Es posible que un dispositivo malicioso no envíe un Informe de Características. El controlador HID Steam no prevé esto actualmente y desreferencia el puntero 'struct hid_report' obtenido de los dispositivos HID sin verificar primero su validez. Vamos a corregir esto.
