  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Use memset_io() to clear QLAFX00 request ring slot\n\nFor QLAFX00 the request ring is ioremapped device I/O memory\n(ha-\u003eiobase + req_que_off), not DMA-coherent RAM, which is why the rest\nof the FX00 path accesses it through memcpy_toio() and the wrt_reg_*\nhelpers. __qla2x00_alloc_iocbs() however zeroed the producer slot with a\nplain memset(). On architectures such as ARM64 a regular memset() may\nemit unaligned or block-zeroing instructions (e.g. DC ZVA) that are\ninvalid on Device memory, leading to a synchronous external abort.\n\nUse memset_io() to clear the slot for QLAFX00, matching the I/O\naccessors used elsewhere on this ring. Other adapters keep the plain\nmemset() on their DMA-coherent rings. The zero-fill is retained for FX00\nbecause its IOCB builders (e.g. qlafx00_fxdisc_iocb()) copy only part of\nthe entry and rely on the unused tail being pre-zeroed.",
