Details

In the Linux kernel, the following vulnerability has been resolved:

net: usb: aqc111: fix error handling of usbnet read calls

Syzkaller, courtesy of syzbot, identified an error (see report [1]) in aqc111 driver, caused by incomplete sanitation of usb read calls' results. This problem is quite similar to the one fixed in commit 920a9fa27e78 ("net: asix: add proper error handling of usb read errors").

For instance, usbnet_read_cmd() may read fewer than 'size' bytes, even if the caller expected the full amount, and aqc111_read_cmd() will not check its result properly. As [1] shows, this may lead to MAC address in aqc111_bind() being only partly initialized, triggering KMSAN warnings.

Fix the issue by verifying that the number of bytes read is as expected and not less.

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 \u0027size\u0027 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"

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
