Description
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.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability occurs in the Linux kernel's HID Steam driver, where it does not check if a pointer to a 'struct hid_report' is valid before dereferencing it. A malicious device can exploit this by not submitting a Feature Report, causing a NULL pointer dereference and potentially leading to a crash or other unintended behavior.


How can this vulnerability impact me? :

The vulnerability can cause the Linux kernel to dereference a NULL pointer when interacting with a malicious HID device, potentially leading to system crashes or denial of service. This could disrupt normal system operations or affect system stability.
