概要
遠端 Azure Linux 主機缺少一個或多個安全性更新。說明
遠端 Azure Linux 3.0 主機上安裝的核心版本比測試版舊。因此，此版本會受到 CVE-2025-38153 公告中提及的一個弱點影響。- 已解決 Linux 核心中的下列弱點：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.
