      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmfmac: make release_scratchbuffers idempotent\n\nbrcmf_pcie_release_scratchbuffers() frees the shared.scratch and\nshared.ringupd DMA buffers with dma_free_coherent() but does not clear\nthe pointers afterwards, unlike the sibling release_ringbuffers() which\nNULLs commonrings/flowrings/idxbuf on release.\n\nBoth the bus_reset .reset callback (brcmf_pcie_reset) and\nbrcmf_pcie_remove() call release_scratchbuffers.  When reset teardown\nhas run before removal, remove's own teardown would call\ndma_free_coherent() a second time on the already-freed DMA allocation.\n\nNULL the pointers after free, matching release_ringbuffers(), so a later\nrelease observes that the allocation has already been released.  This\npatch makes repeated sequential release safe; the reset-work lifetime is\nhandled separately by the following patch.\n\nThis issue was found by an in-house static analysis tool.",
