Linux Distros 未修补的漏洞：CVE-2026-23167
medium Nessus 插件 ID 299320

简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- nfcnci修复了 rfkill 和 nci_unregister_device() 之间的争用。 syzbot 在无重现的情况下报告了低于 [0] 的 splat。这表示在通过 rfkill 调用 nci_close_device() 之前结构 nci_dev.cmd_wq 已遭到破坏。 nci_dev.cmd_wq 仅在 nci_unregister_device() 中损坏我认为当 syzbot close()d virtual_ncidev 的 fd 时从 virtual_ncidev_close() 调用该函数。问题在于 nci_unregister_device() 先破坏 nci_dev.cmd_wq然后调用 nfc_unregister_device()这将通过 rfkill_unregister() 从 rfkill 删除设备。因此即使在破坏 nci_dev.cmd_wq 之后设备仍可通过 rfkill 可见。我们首先在 nci_unregister_device() 中从 rfkill 取消注册设备。请注意我们无法在 nci_close_device() 之前调用 nfc_unregister_device()因为 1) nfc_unregister_device() 调用 device_del()后者释放由 devm_kzalloc() 分配并链接到 ndev->conn_info_list 的所有内存 2) nci_rx_work() 可尝试将 nci_conn_info 排入 ndev 队列->可能遭到泄露的conn_info_list 因此nfc_unregister_device() 被拆分为两个函数所以只能删除 nci_close_device() 之前的 rfkill 接口。 [0]DEBUG_LOCKS_WARN_ON(1) 警告
