      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Fix out-of-bound memcpy() during ethtool -w\n\nWhen retrieving the FW coredump using ethtool, it can sometimes cause\nmemory corruption:\n\nBUG: KFENCE: memory corruption in __bnxt_get_coredump+0x3ef/0x670 [bnxt_en]\nCorrupted memory at 0x000000008f0f30e8 [ ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ] (in kfence-#45):\n__bnxt_get_coredump+0x3ef/0x670 [bnxt_en]\nethtool_get_dump_data+0xdc/0x1a0\n__dev_ethtool+0xa1e/0x1af0\ndev_ethtool+0xa8/0x170\ndev_ioctl+0x1b5/0x580\nsock_do_ioctl+0xab/0xf0\nsock_ioctl+0x1ce/0x2e0\n__x64_sys_ioctl+0x87/0xc0\ndo_syscall_64+0x5c/0xf0\nentry_SYSCALL_64_after_hwframe+0x78/0x80\n\n...\n\nThis happens when copying the coredump segment list in\nbnxt_hwrm_dbg_dma_data() with the HWRM_DBG_COREDUMP_LIST FW command.\nThe info->dest_buf buffer is allocated based on the number of coredump\nsegments returned by the FW.  The segment list is then DMA'ed by\nthe FW and the length of the DMA is returned by FW.  The driver then\ncopies this DMA'ed segment list to info->dest_buf.\n\nIn some cases, this DMA length may exceed the info->dest_buf length\nand cause the above BUG condition.  Fix it by capping the copy\nlength to not exceed the length of info->dest_buf.  The extra\nDMA data contains no useful information.\n\nThis code path is shared for the HWRM_DBG_COREDUMP_LIST and the\nHWRM_DBG_COREDUMP_RETRIEVE FW commands.  The buffering is different\nfor these 2 FW commands.  To simplify the logic, we need to move\nthe line to adjust the buffer length for HWRM_DBG_COREDUMP_RETRIEVE\nup, so that the new check to cap the copy length will work for both\ncommands.",
