Detailsinfo

A vulnerability was found in Linux Kernel up to 4.19.256/5.4.211/5.10.140/5.15.64/5.19.6. It has been classified as critical. This affects the function hid_report of the component HID Steam Driver. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2022-49984 since 06/18/2025. Technical details are known, but no exploit is available.

Upgrading to version 4.19.257, 5.4.212, 5.10.141, 5.15.65 or 5.19.7 eliminates this vulnerability. Applying the patch c20d03b82a2e3ddbb555dad4d4f3374a9763222c/fa2b822d86be5b5ad54fe4fa2daca464e71ff90a/dc815761948ab5b8c94db6cb53c95103588f16ae/989560b6d9e00d99e07bc33067fa1c770994bf4d/dee1e51b54794e90763e70a3c78f27ba4fa930ec/cd11d1a6114bd4bc6450ae59f6e110ec47362126 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
