  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmfmac: Fix potential kernel oops when probe fails\n\nWhen probe of the sdio brcmfmac device fails for some reasons (i.e.\nmissing firmware), the sdiodev-\u003ebus is set to error instead of NULL, thus\nthe cleanup later in brcmf_sdio_remove() tries to free resources via\ninvalid bus pointer. This happens because sdiodev-\u003ebus is set 2 times:\nfirst in brcmf_sdio_probe() and second time in brcmf_sdiod_probe(). Fix\nthis by chaning the brcmf_sdio_probe() function to return the error code\nand set sdio-\u003ebus only there.",
