Description OSIDB Bzimport 2025-06-18 12:01:27 UTC
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.
