Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - arm64：mm：修正 show_pte（） 中的無鎖定頁面表格遍歷 show_pte（） 以無鎖定方式遍歷頁面表格，並且可以在啟用中斷的情況下執行。並行拆卸可以在遍歷表格頁面時釋放該頁面。它也可以在 show_pte（） 檢查後清除父項目;然後，常規 pXd_offset（） 協助程式重新讀取已清除的項目，並可能衍生出虛假的較低層級指標並再次出錯。像 gup_fast（） 一樣，將無鎖定偏移協助程式與已儲存的父項目一起使用，並將已儲存的 PMD 傳遞給 pte_offset_map（）。針對工作頁面數據表，arm64 會選取 MMU_GATHER_RCU_TABLE_FREE。停用遍歷周圍的本機中斷，以延遲 RCU 延遲的資料表釋放，並封鎖 tlb_remove_table_sync_one（） IPI，直到遍歷完成為止。在標頭列印後放置 IRQ 防護罩。這不會使輸出成為一致的快照集，但可防止工作頁面表格遍歷取消參照已釋放的資料表頁面，或從不同的父項值衍生指標。（CVE-2026-93239）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

AlmaLinux 9.2 主機已安裝的套件會受到 TuxCare ALMALINUX9.2：CLSA-2026：1792243434 公告中提及的多個弱點影響。

  - 已解決 Linux 核心中的下列弱點：ethernet: hisilicon: hns:
    hns_dsaf_misc: fix a possible array overflow in hns_dsaf_ge_srst_by_port() The if statement: if (port >= DSAF_GE_NUM) return; limits the value of port less than DSAF_GE_NUM (i.e., 8). However, if the value of port is 6 or 7, an array overflow could occur: port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off;
    because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6). To fix this possible array overflow, we first check port and if it is greater than or equal to DSAF_MAX_PORT_NUM, the function returns. (CVE-2021-47548)

  - 已解決 Linux 核心中的下列弱點：dm: call the resume method on internal suspend There is this reported crash when experimenting with the lvm2 testsuite. The list corruption is caused by the fact that the postsuspend and resume methods were not paired correctly; there were two consecutive calls to the origin_postsuspend function. The second call attempts to remove the hash_list entry from a list, while it was already removed by the first call. Fix __dm_internal_resume so that it calls the preresume and resume methods of the table's targets. If a preresume method of some target fails, we are in a tricky situation. We can't return an error because dm_internal_resume isn't supposed to return errors. We can't return success, because then the resume and postsuspend methods would not be paired correctly. So, we set the DMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace tools, but it won't cause a kernel crash. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:56! invalid opcode: 0000 [#1] PREEMPT SMP CPU: 1 PID: 8343 Comm: dmsetup Not tainted 6.8.0-rc6 #4 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 RIP:
