      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath10k: snoc: use memcpy_fromio() for MSA ramdump\n\nOn WCN3990/SNOC the MSA region is mapped with devm_memremap(MEMREMAP_WT).\nOn arm64 such a mapping is not Normal-cacheable, so unaligned accesses to\nit are not permitted. ath10k_msa_dump_memory() copies the region with a\nplain memcpy(), whose optimized __pi_memcpy_generic implementation issues\nwide/unaligned loads. This triggers an alignment fault (FSC=0x21) Oops in\nath10k_snoc_fw_crashed_dump() while collecting the devcoredump:\n\n  Unable to handle kernel paging request ... FSC=0x21: alignment fault\n  pc : __pi_memcpy_generic\n  lr : ath10k_snoc_fw_crashed_dump [ath10k_snoc]\n\nThe Oops both leaves the firmware RAM dump buffer zeroed (no dump is\ncaptured) and crashes the kernel, which in turn breaks modem SSR\nrecovery.\n\nUse memcpy_fromio(), which only performs accesses that are valid for such\na device-memory mapping. The generic memcpy_fromio() implementation aligns\nthe source before issuing word-sized reads and stores the destination with\nput_unaligned(), so it is also safe for the coherent DMA allocation used on\nthe non-reserved-memory path. ath11k and ath12k use the same pattern\nwhen copying target memory into crash dumps, so call it unconditionally\nhere too.\nThe MEMREMAP_WT pointer is a plain void *, so an explicit __iomem cast is\nneeded; use __force to keep sparse happy.\n\nTested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.3.7.c5-00107-QCAHLSWMTPL-1",
