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。

  - wifi：修复拆分 6 GHz 扫描失败时的泄漏 如果 cfg80211_scan（） 失败，将泄漏 rdev->int_scan_req。请注意，它应该在 ___cfg80211_scan_done（） 时释放，但这种情况不会发生，因为 rdev->scan_req 在该时也是 NULL，从而导致从释放函数提早返回。未引用的对象0xffff8881161d0800（大小 512）：comm wpa_supplicant、pid 379、jiffies 4294749765 hex 转储（前 32 字节）：00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................00 00 00 00 00 00 00 00 00 f0 81 13 16 81 88 ff ff ................回溯 （CRC c867fdb6）：kmemleak_alloc+0x89/0x90
