  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: brcmfmac: initialize SDIO data work before cleanup  brcmf_sdio_probe() stores the newly allocated bus in sdiodev-\u003ebus before allocating the ordered workqueue. If that allocation fails, the function jumps to fail and calls brcmf_sdio_remove().  brcmf_sdio_remove() unconditionally cancels bus-\u003edatawork. Initialize the work item before the first failure path that can reach brcmf_sdio_remove(), so the cleanup path always observes a valid work object.  This issue was found by our static analysis tool and then confirmed by manual review of the probe error path and the remove-time work drain. The problem pattern is an early setup failure that reaches a cleanup helper which cancels an embedded work item before its initializer has run.  A QEMU PoC forced alloc_ordered_workqueue() to fail at the same point in brcmf_sdio_probe(), before INIT_WORK(\u0026bus-\u003edatawork) is reached. The resulting fail path calls brcmf_sdio_remove(), and DEBUG_OBJECTS reports the invalid work drain with brcmf_sdio_probe() and brcmf_sdio_remove() in the stack.",
