This problem is quite similar to the one fixed in commit\n920a9fa27e78 (\"net: asix: add proper error handling of usb read errors\").\n\nFor instance, usbnet_read_cmd() may read fewer than 'size' bytes,\neven if the caller expected the full amount, and aqc111_read_cmd()\nwill not check its result properly. As [1] shows, this may lead\nto MAC address in aqc111_bind() being only partly initialized,\ntriggering KMSAN warnings.\n\nFix the issue by verifying that the number of bytes read is\nas expected and not less.\n\n[1] Partial syzbot report:\nBUG: KMSAN: uninit-value in is_valid_ether_addr include/linux/etherdevice.h:208 [inline]\nBUG: KMSAN: uninit-value in usbnet_probe+0x2e57/0x4390 drivers/net/usb/usbnet.c:1830\n is_valid_ether_addr include/linux/etherdevice.h:208 [inline]\n usbnet_probe+0x2e57/0x4390 drivers/net/usb/usbnet.c:1830\n usb_probe_interface+0xd01/0x1310 drivers/usb/core/driver.c:396\n call_driver_probe drivers/base/dd.c:-1 [inline]\n really_probe+0x4d1/0xd90 drivers/base/dd.c:658\n __driver_probe_device+0x268/0x380 drivers/base/dd.c:800\n...\n\nUninit was stored to memory at:\n dev_addr_mod+0xb0/0x550 net/core/dev_addr_lists.c:582\n __dev_addr_set include/linux/netdevice.h:4874 [inline]\n eth_hw_addr_set include/linux/etherdevice.h:325 [inline]\n aqc111_bind+0x35f/0x1150 drivers/net/usb/aqc111.c:717\n usbnet_probe+0xbe6/0x4390 drivers/net/usb/usbnet.c:1772\n usb_probe_interface+0xd01/0x1310 drivers/usb/core/driver.c:396\n...\n\nUninit was stored to memory at:\n ether_addr_copy include/linux/etherdevice.h:305 [inline]\n aqc111_read_perm_mac drivers/net/usb/aqc111.c:663 [inline]\n aqc111_bind+0x794/0x1150 drivers/net/usb/aqc111.c:713\n usbnet_probe+0xbe6/0x4390 drivers/net/usb/usbnet.c:1772\n usb_probe_interface+0xd01/0x1310 drivers/usb/core/driver.c:396\n call_driver_probe drivers/base/dd.c:-1 [inline]\n...\n\nLocal variable buf.i created at:\n aqc111_read_perm_mac drivers/net/usb/aqc111.c:656 [inline]\n aqc111_bind+0x221/0x1150 drivers/net/usb/aqc111.c:713\n usbnet_probe+0xbe6/0x4390 drivers/net/usb/usbnet.c:1772", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "8c97655275482ef5384ce0501640630a0fc0f6f4" }, { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "11273279012c922f37cfb4dd95d142803fc07b98" }, { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "f398d2dfe450ce2c031d10b585448862d74a0501" }, { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "acb47a40b5e38be03ef659b7bacdddc592ed73b7" }, { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "60790d287c1a1ced3554d4a87c2f27bf299a932a" }, { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "30a9e834c74e260533b8d0885e3c89f6f32f7993" }, { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "7c01863b1c47f040d9674171e77789a423b9b128" }, { "version": "df2d59a2ab6c9ceac2c4104272fce03493b8f62f", "status": "affected", "versionType": "git", "lessThan": "405b0d610745fb5e84fc2961d9b960abb9f3d107" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "5.0", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "5.0" }, { "version": "5.4.295", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.4.*" }, { "version": "5.10.239", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.186", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.142", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.94", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.34", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.15.3", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.15.*" }, { "version": "6.16", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
