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。

  - atmclip修复 clip_push() 的无限递归调用。 syzbot 报告了以下错误消息。 [0] 如果多次调用 ioctl(ATMARP_MKIP)会发生这种情况。在第一次调用期间clip_mkip() 将 clip_push() 设置为 vcc->push()第二次调用时将其复制到 clip_vcc->old_push()。之后当关闭套接字时vcc_destroy_socket() 会将空 skb 传递给 clip_push()这会调用 clip_vcc->old_push()从而触发无限递归。让我们通过检查 vcc->user_back 来阻止第二个 ioctl(ATMARP_MKIP)它由第一个调用分配为 clip_vcc。另请注意我们使用 lock_sock() 是为了防止 racy 调用。 [0]
