  "description": "In the Linux kernel, the following vulnerability has been resolved:  wifi: brcmfmac: Check for probe() id argument being NULL  The probe() id argument may be NULL in 2 scenarios:  1. brcmf_pcie_pm_leave_D3() calling brcmf_pcie_probe() to reprobe    the device.  2. If a user tries to manually bind the driver from sysfs then the sdio /    pcie / usb probe() function gets called with NULL as id argument.  1. Is being hit by users causing the following oops on resume and causing wifi to stop working:  BUG: kernel NULL pointer dereference, address: 0000000000000018 \u003Csnip\u003E Hardware name: Dell Inc.

In the PCI and USB cases try a manual lookup of the id so that manually binding the driver through sysfs and more importantly brcmf_pcie_probe() on resume will work.  For the SDIO case there is no helper to do a manual sdio_device_id lookup, so just directly error out on a NULL id there.",
