"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusbip: vhci_hcd: fix NULL deref in status_show_vhci\n\nplatform_get_drvdata() can return NULL if a VHCI host controller's\nprobe failed (e.g. due to USB bus number exhaustion). status_show_vhci()\nchecked for a NULL pdev but not for a NULL hcd returned by\nplatform_get_drvdata(). Passing NULL to hcd_to_vhci_hcd() does not\nreturn NULL - it returns a pointer offset of 0x260, causing a NULL\npointer dereference when that value is subsequently dereferenced.\n\nAdd a NULL check on hcd before calling hcd_to_vhci_hcd(). Move\nstatus_show_not_ready() above status_show_vhci() to make it callable\nfrom the new error path without a forward declaration."
