Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - Linux カーネルでは、以下の脆弱性が解決されています: nvme-tcp: remove tag set when second admin queue config fails Commit 104d0e2f6222 (nvme-fabrics: reset admin connection for secure concatenation) modified nvme_tcp_setup_ctrl() to call nvme_tcp_configure_admin_queue() twice. The first call prepares for DH-CHAP negotitation, and the second call is required for secure concatenation. However, this change triggered BUG KASAN slab-use-after- free in blk_mq_queue_tag_busy_iter(). This BUG can be recreated by repeating the blktests test case nvme/063 a few times [1]. When the BUG happens, nvme_tcp_create_ctrl() fails in the call chain below: nvme_tcp_create_ctrl() nvme_tcp_alloc_ctrl() new=true ... Alloc nvme_tcp_ctrl and admin_tag_set nvme_tcp_setup_ctrl() new=true nvme_tcp_configure_admin_queue() new=true ... Succeed nvme_alloc_admin_tag_set() ... Alloc the tag set for admin_tag_set nvme_stop_keep_alive() nvme_tcp_teardown_admin_queue() remove=false nvme_tcp_configure_admin_queue() new=false nvme_tcp_alloc_admin_queue() ... Fail, but do not call nvme_remove_admin_tag_set() nvme_uninit_ctrl() nvme_put_ctrl() ... Free up the nvme_tcp_ctrl and admin_tag_set The first call of nvme_tcp_configure_admin_queue() succeeds with new=true argument. The second call fails with new=false argument. This second call does not call nvme_remove_admin_tag_set() on failure, due to the new=false argument. Then the admin tag set is not removed. However, nvme_tcp_create_ctrl() assumes that nvme_tcp_setup_ctrl() would call nvme_remove_admin_tag_set(). Then it frees up struct nvme_tcp_ctrl which has admin_tag_set field. Later on, the timeout handler accesses the admin_tag_set field and causes the BUG KASAN slab-use-after-free. To not leave the admin tag set, call nvme_remove_admin_tag_set() when the second nvme_tcp_configure_admin_queue() call fails. Do not return from nvme_tcp_setup_ctrl() on failure. Instead, jump to destroy_admin go-to label to call nvme_tcp_teardown_admin_queue() which calls nvme_remove_admin_tag_set(). (CVE-2025-38209)

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: remove tag set when second     admin queue config fails Commit 104d0e2f6222 (nvme-fabrics: reset admin connection for secure     concatenation) modified nvme_tcp_setup_ctrl() to call nvme_tcp_configure_admin_queue() twice. The first     call prepares for DH-CHAP negotitation, and the second call is required for secure concatenation. However,     this change triggered BUG KASAN slab-use-after- free in blk_mq_queue_tag_busy_iter(). This BUG can be     recreated by repeating the blktests test case nvme/063 a few times [1]. When the BUG happens,     nvme_tcp_create_ctrl() fails in the call chain below: nvme_tcp_create_ctrl() nvme_tcp_alloc_ctrl()     new=true ... Alloc nvme_tcp_ctrl and admin_tag_set nvme_tcp_setup_ctrl() new=true     nvme_tcp_configure_admin_queue() new=true ... Succeed nvme_alloc_admin_tag_set() ... Alloc the tag set for     admin_tag_set nvme_stop_keep_alive() nvme_tcp_teardown_admin_queue() remove=false     nvme_tcp_configure_admin_queue() new=false nvme_tcp_alloc_admin_queue() ... Fail, but do not call     nvme_remove_admin_tag_set() nvme_uninit_ctrl() nvme_put_ctrl() ... Free up the nvme_tcp_ctrl and     admin_tag_set The first call of nvme_tcp_configure_admin_queue() succeeds with new=true argument. The     second call fails with new=false argument. This second call does not call nvme_remove_admin_tag_set() on     failure, due to the new=false argument. Then the admin tag set is not removed. However,     nvme_tcp_create_ctrl() assumes that nvme_tcp_setup_ctrl() would call nvme_remove_admin_tag_set(). Then it     frees up struct nvme_tcp_ctrl which has admin_tag_set field. Later on, the timeout handler accesses the     admin_tag_set field and causes the BUG KASAN slab-use-after-free. To not leave the admin tag set, call     nvme_remove_admin_tag_set() when the second nvme_tcp_configure_admin_queue() call fails. Do not return     from nvme_tcp_setup_ctrl() on failure. Instead, jump to destroy_admin go-to label to call     nvme_tcp_teardown_admin_queue() which calls nvme_remove_admin_tag_set(). (CVE-2025-38209)

Note that Nessus relies on the presence of the package as reported by the vendor.
