Passing NULL to hcd_to_vhci_hcd() does not return NULL - it returns a pointer offset of 0x260, causing a NULL pointer dereference when that value is subsequently dereferenced.</p> <p>Add a NULL check on hcd before calling hcd_to_vhci_hcd(). Move status_show_not_ready() above status_show_vhci() to make it callable from the new error path without a forward declaration.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>usbip: vhci_hcd: fix NULL deref in status_show_vhci</p> <p>platform_get_drvdata() can return NULL if a VHCI host controller&#39;s probe failed (e.g. due to USB bus number exhaustion). status_show_vhci() checked for a NULL pdev but not for a NULL hcd returned by platform_get_drvdata().
