      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\narm64: dts: qcom: monaco: Reserve full Gunyah metadata region\n\nWe observe spurious \"Synchronous External Abort\" exceptions\n(ESR=0x96000010) and kernel crashes on Monaco-based platforms.\nThese faults are caused by the kernel inadvertently accessing\nhypervisor-owned memory that is not properly marked as reserved.\n\n>From boot log, The Qualcomm hypervisor reports the memory range\nat 0x91a80000 of size 0x80000 (512 KiB) as hypervisor-owned:\nqhee_hyp_assign_remove_memory: 0x91a80000/0x80000 -> ret 0\n\nHowever, the EFI memory map provided by firmware only reserves the\nsubrange 0x91a40000–0x91a87fff (288 KiB). The remaining portion\n(0x91a88000–0x91afffff) is incorrectly reported as conventional\nmemory (from efi debug):\nefi:   0x000091a40000-0x000091a87fff [Reserved...]\nefi:   0x000091a88000-0x0000938fffff [Conventional...]\n\nAs a result, the allocator may hand out PFNs inside the hypervisor\nowned region, causing fatal aborts when the kernel accesses those\naddresses.\n\nAdd a reserved-memory carveout for the Gunyah hypervisor metadata\nat 0x91a80000 (512 KiB) and mark it as no-map so Linux does not\nmap or allocate from this area.\n\nFor the record:\nHyp version: gunyah-e78adb36e debug (2025-11-17 05:38:05 UTC)\nUEFI Ver: 6.0.260122.BOOT.MXF.1.0.c1-00449-KODIAKLA-1",
