AlmaLinux 9.2 ホストには、TuxCare ALMALINUX9.2:CLSA-2026:1792243434アドバイザリに記載されている複数の脆弱性の影響を受ける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: 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)

  - Linux カーネルでは、以下の脆弱性が解決されています: 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:

Thus we need to extend modes[] the same protection or by the time we use it the elements may already be pointing to freed/reused memory. (CVE-2024-35950)

  - scsi:qla2xxx:キュー切断時の qpair 作業の use-after-free を修正します 応答キュー MSI-X ハンドラー qla2xxx_msix_rsp_q() は、queue_work(ha->wq、&qpair->q_work) を介して qla_do_work() をスケジュールします。qla_do_work() は qpair(vha、rsp)を逆参照し、qpair->qp_lock を取得します。ティアダウン中に、qla2xxx_delete_qpair()は応答キューを削除し、応答キューはqla25xx_free_rsp_que()のfree_irq()を呼び出してからキューとqpairを解放します。free_irq() は hardirq ハンドラーの実行を待機しますが、ha->wq にすでに配置された作業をキャンセルしません。その後、未解決のq_workが、解放された qpair および応答キューに対して qla_do_work() を実行することで、use-after-free が発生します。これは特に完全なアダプター切断中に発生し、キューペアが解放された後にdestroy_workqueue(ha->wq)が保留中の作業を実行するように強制します。free_irq() が割り込みをリリースした後、応答キューと qpair メモリが解放される前に(フラッシュされたハンドラーが有効なメモリを引き続き確認するため)、qla25xx_free_rsp_que() の cancel_work_sync() で作業項目をフラッシュします。rsp->qpair と ha->wq でガードを行い、INIT_WORK() 条件を一致させ、初期化されていないwork_structでの操作を回避します。(CVE-2026-97536)

CentOS Linux 8.4 ホストには、TuxCare CENTOS8.4:CLSA-2026:1792243729アドバイザリに記載されている複数の脆弱性の影響を受けるパッケージがインストールされています。

  - 5.14.15 より前の Linux カーネルで問題が発見されました。drivers/isdn/capi/kcapi.c の detach_capi_ctr 関数に array-index-out-of-boundsの欠陥があります。(CVE-2021-43389)

  - Linux カーネルでは、以下の脆弱性が解決されています: isdn: cpai: check ctr->cnr to avoid array index out of bound The cmtp_add_connection() would add a cmtp session to a controller and run a kernel thread to process cmtp. __module_get(THIS_MODULE); session->task = kthread_run(cmtp_session, session, kcmtpd_ctr_%d, session->num); During this process, the kernel thread would call detach_capi_ctr() to detach a register controller. if the controller was not attached yet, detach_capi_ctr() would trigger an array-index-out-bounds bug. [ 46.866069][ T6479] UBSAN: array-index-out-of-bounds in drivers/isdn/capi/kcapi.c:483:21 [ 46.867196][ T6479] index -1 is out of range for type 'capi_ctr *[32]' [ 46.867982][ T6479] CPU: 1 PID: 6479 Comm: kcmtpd_ctr_0 Not tainted 5.15.0-rc2+ #8 [46.869002][ T6479] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 [46.870107][ T6479] Call Trace: [ 46.870473][ T6479] dump_stack_lvl+0x57/0x7d [ 46.870974][ T6479] ubsan_epilogue+0x5/0x40 [ 46.871458][ T6479] __ubsan_handle_out_of_bounds.cold+0x43/0x48 [ 46.872135][T6479] detach_capi_ctr+0x64/0xc0 [ 46.872639][ T6479] cmtp_session+0x5c8/0x5d0 [ 46.873131][ T6479] ?

  - Linux カーネルでは、以下の脆弱性が解決されています: Drivers: hv: vmbus: Use after free in
    __vmbus_open() The open_info variable is added to the &vmbus_connection.chn_msg_list, but the error handling frees open_info without removing it from the list. This will result in a use after free. First remove it from the list, and then free it. (CVE-2021-47049)

  - Linux カーネルでは、以下の脆弱性が解決されています: scsi: mpt3sas: Fix kernel panic during drive powercycle test While looping over shost's sdev list it is possible that one of the drives is getting removed and its sas_target object is freed but its sdev object remains intact. Consequently, a kernel panic can occur while the driver is trying to access the sas_address field of sas_target object without also checking the sas_target object for NULL. (CVE-2021-47565)

  - Linux カーネルでは、以下の脆弱性が解決されています: igbvf: fix double free in `igbvf_probe` In `igbvf_probe`, if register_netdev() fails, the program will go to label err_hw_init, and then to label err_ioremap. In free_netdev() which is just below label err_ioremap, there is `list_for_each_entry_safe` and `netif_napi_del` which aims to delete all entries in `dev->napi_list`. The program has added an entry `adapter->rx_ring->napi` which is added by `netif_napi_add` in igbvf_alloc_queues(). However, adapter->rx_ring has been freed below label err_hw_init. So this a UAF. In terms of how to patch the problem, we can refer to igbvf_remove() and delete the entry before `adapter->rx_ring`. The KASAN logs are as follows: [ 35.126075] BUG: KASAN: use-after-free in free_netdev+0x1fd/0x450 [ 35.127170] Read of size 8 at addr ffff88810126d990 by task modprobe/366 [35.128360] [ 35.128643] CPU: 1 PID: 366 Comm: modprobe Not tainted 5.15.0-rc2+ #14 [ 35.129789] Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.12.0-59-gc9ba5276e321-prebuilt.qemu.org 04/01/2014 [35.131749] Call Trace: [ 35.132199] dump_stack_lvl+0x59/0x7b [ 35.132865] print_address_description+0x7c/0x3b0 [ 35.133707] ? free_netdev+0x1fd/0x450 [ 35.134378]
