In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix use-after-free of qpair work on queue teardown The response queue MSI-X handler qla2xxx_msix_rsp_q() schedules qla_do_work() via queue_work(ha->wq, &qpair->q_work). qla_do_work() dereferences the qpair (vha, rsp) and takes qpair->qp_lock. During teardown, qla2xxx_delete_qpair() deletes the response queue, which calls free_irq() in qla25xx_free_rsp_que(), and then frees the queue and the qpair. free_irq() waits for running hardirq handlers but does not cancel work already placed on ha->wq. A still-pending q_work then runs qla_do_work() against the freed qpair and response queue, causing a use-after-free. This is especially likely during full adapter teardown, where destroy_workqueue(ha->wq) forces pending work to run after the queue pairs have been freed. Flush the work item with cancel_work_sync() in qla25xx_free_rsp_que() after free_irq() has released the interrupt (so no new work can be queued) and before the response queue and qpair memory are freed (so the flushed handler still sees valid memory). Guard on rsp->qpair and ha->wq to match the INIT_WORK() condition and avoid operating on an uninitialized work_struct.

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1792234299 advisory.

  - nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote     attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte     nfta_payload attribute, an skb_pull can encounter a negative skb->len. (CVE-2022-36946)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: Fix a memory     corruption issue A few lines above, space is kzalloc()'ed for: sizeof(struct iwl_nvm_data) + sizeof(struct     ieee80211_channel) + sizeof(struct ieee80211_rate) 'mvm->nvm_data' is a 'struct iwl_nvm_data', so it is     fine. At the end of this structure, there is the 'channels' flex array. Each element is of type 'struct     ieee80211_channel'. So only 1 element is allocated in this array. When doing:
    mvm->nvm_data->bands[0].channels = mvm->nvm_data->channels; We point at the first element of the     'channels' flex array. So this is fine. However, when doing: mvm->nvm_data->bands[0].bitrates = (void
    *)((u8 *)mvm->nvm_data->channels + 1); because of the (u8 *) cast, we add only 1 to the address of the     beginning of the flex array. It is likely that we want point at the 'struct ieee80211_rate' allocated just     after. Remove the spurious casting so that the pointer arithmetic works as expected. (CVE-2023-52531)

  - In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Don't (re)check L1     intercepts when completing userspace I/O When completing emulation of instruction that generated a     userspace exit for I/O, don't recheck L1 intercepts as KVM has already finished that phase of instruction     execution, i.e. has already committed to allowing L2 to perform I/O. If L1 (or host userspace) modifies     the I/O permission bitmaps during the exit to userspace, KVM will treat the access as being intercepted     despite already having emulated the I/O access. Pivot on EMULTYPE_NO_DECODE to detect that KVM is     completing emulation. Of the three users of EMULTYPE_NO_DECODE, only complete_emulated_io() (the intended     recipient) can reach the code in question. gp_interception()'s use is mutually exclusive with     is_guest_mode(), and complete_emulated_insn_gp() unconditionally pairs EMULTYPE_NO_DECODE with     EMULTYPE_SKIP. The bad behavior was detected by a syzkaller program that toggles port I/O interception     during the userspace I/O exit, ultimately resulting in a WARN on vcpu->arch.pio.count being non-zero due     to KVM no completing emulation of the I/O instruction.

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: fix use-after-free     on registration failure Make sure to release the sibling interfaces in case controller registration fails     to avoid use-after-free and double-free when they are eventually disconnected. This issue was reported by     Sashiko while reviewing a fix for a wakeup source leak in the btusb probe errors paths. (CVE-2026-64471)

  - In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire: isight: bound the     sample count to the packet payload isight_packet() takes the frame count from the device iso packet and     checks it only against the device claimed iso length. count = be32_to_cpu(payload->sample_count); if     (likely(count <= (length - 16) / 4)) isight_samples(isight, payload->samples, count); length is the iso     header data_length. It can be up to 0xffff. So the gate allows a count up to about 16379. isight_samples()     then copies count frames out of payload->samples into the PCM DMA buffer. payload->samples holds only 2 *     MAX_FRAMES_PER_PACKET values. The device multiplexes two samples per frame. A count past     MAX_FRAMES_PER_PACKET reads past the payload. A count past the buffer size writes past runtime->dma_area.
    The smallest PCM buffer is larger than MAX_FRAMES_PER_PACKET. Bounding the count to MAX_FRAMES_PER_PACKET     keeps both the read and the write in range. A malicious or faulty Apple iSight on the FireWire bus reaches     this during a normal capture. Add the MAX_FRAMES_PER_PACKET bound to the gate. (CVE-2026-64483)

The CentOS Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS6:CLSA-2026:1791949745 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: HID: core: zero-initialize the report     buffer Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it     during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted     report. (CVE-2024-50302)

  - In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential out-of-     bound accesses for Extigy and Mbox devices A bogus device can provide a bNumConfigurations value that     exceeds the initial value used in usb_get_configuration for allocating dev->config. This can lead to out-     of-bounds accesses later, e.g. in usb_destroy_configuration. (CVE-2024-53197)

  - In the Linux kernel, the following vulnerability has been resolved: smb: client: reject userspace     cifs.spnego descriptions cifs.spnego key descriptions contain authority-bearing fields such as pid, uid,     creduid, and upcall_target that cifs.upcall treats as kernel-originating inputs. However, userspace can     also create keys of this type through request_key(2) or add_key(2), allowing those fields to be supplied     without CIFS origin. Only accept cifs.spnego descriptions while CIFS is using its private spnego_cred to     request the key. (CVE-2026-46243)

  - In the Linux kernel, the following vulnerability has been resolved: Bluetooth: serialize accept_q access     bt_sock_poll() walks the accept queue without synchronization, while child teardown can unlink the same     socket and drop its last reference. The unsynchronized accept queue walk has existed since the initial     Bluetooth import. Protect accept_q with a dedicated lock for queue updates and polling. Also rework     bt_accept_dequeue() to take temporary child references under the queue lock before dropping it and locking     the child socket. (CVE-2026-52918)

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: bridge: make ebt_snat ARP     rewrite writable The ebtables SNAT target keeps the Ethernet source address rewrite behind     skb_ensure_writable(skb, 0). This is intentional: at the bridge ebtables hooks the Ethernet header is     addressed through skb_mac_header()/eth_hdr(), while skb->data points at the Ethernet payload. Asking     skb_ensure_writable() for ETH_HLEN bytes would check the payload, not the Ethernet header, and would     reintroduce the small packet regression fixed by commit 63137bc5882a. However, the optional ARP sender     hardware address rewrite is different. It writes through skb_store_bits() at an offset relative to     skb->data: skb_store_bits(skb, sizeof(struct arphdr), info->mac, ETH_ALEN) skb_header_pointer() only     safely reads the ARP header; it does not make the later sender hardware address range writable. If that     range is still held in a nonlinear skb fragment backed by a splice-imported file page, skb_store_bits()     maps the frag page and copies the new MAC address directly into it. Ensure the ARP SHA range is writable     before reading the ARP header and before calling skb_store_bits(). (CVE-2026-53266)

The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2026:1792247642 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: ethtool: do not perform operations on     net devices being unregistered There is a short period between a net device starts to be unregistered and     when it is actually gone. In that time frame ethtool operations could still be performed, which might end     up in unwanted or undefined behaviours[1]. Do not allow ethtool operations after a net device starts its     unregistration. This patch targets the netlink part as the ioctl one isn't affected: the reference to the     net device is taken and the operation is executed within an rtnl lock section and the net device won't be     found after unregister. [1] For example adding Tx queues after unregister ends up in NULL pointer     exceptions and UaFs, such as: BUG: KASAN: use-after-free in kobject_get+0x14/0x90 Read of size 1 at addr     ffff88801961248c by task ethtool/755 CPU: 0 PID: 755 Comm: ethtool Not tainted 5.15.0-rc6+ #778 Hardware     name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-4.fc34 04/014 Call Trace:

  - In the Linux kernel, the following vulnerability has been resolved: nvme-tcp: fix UAF when detecting     digest errors We should also bail from the io_work loop when we set rd_enabled to true, so we don't     attempt to read data from the socket when the TCP stream is already out-of-sync or corrupted.
    (CVE-2022-48686)

  - In the Linux kernel, the following vulnerability has been resolved: net: bonding: fix use-after-free after     802.3ad slave unbind commit 0622cab0341c (bonding: fix 802.3ad aggregator reselection), resolve case,     when there is several aggregation groups in the same bond. bond_3ad_unbind_slave will invalidate (clear)     aggregator when __agg_active_ports return zero. So, ad_clear_agg can be executed even, when     num_of_ports!=0. Than bond_3ad_unbind_slave can be executed again for, previously cleared aggregator.
    NOTE: at this time bond_3ad_unbind_slave will not update slave ports list, because lag_ports==NULL. So,     here we got slave ports, pointing to freed aggregator memory. Fix with checking actual number of ports in     group (as was before commit 0622cab0341c (bonding: fix 802.3ad aggregator reselection) ), before     ad_clear_agg(). The KASAN logs are as follows: [ 767.617392]     ================================================================== [ 767.630776] BUG: KASAN: use-after-     free in bond_3ad_state_machine_handler+0x13dc/0x1470 [ 767.638764] Read of size 2 at addr ffff00011ba9d430     by task kworker/u8:7/767 [ 767.647361] CPU: 3 PID: 767 Comm: kworker/u8:7 Tainted: G O 5.15.11 #15 [     767.655329] Hardware name: DNI AmazonGo1 A7040 board (DT) [ 767.660760] Workqueue: lacp_1     bond_3ad_state_machine_handler [ 767.666468] Call trace: [ 767.668930] dump_backtrace+0x0/0x2d0 [     767.672625] show_stack+0x24/0x30 [ 767.675965] dump_stack_lvl+0x68/0x84 [ 767.679659]     print_address_description.constprop.0+0x74/0x2b8 [ 767.685451] kasan_report+0x1f0/0x260 [ 767.689148]

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Do mark_chain_precision for     ARG_CONST_ALLOC_SIZE_OR_ZERO Precision markers need to be propagated whenever we have an ARG_CONST_* style     argument, as the verifier cannot consider imprecise scalars to be equivalent for the purposes of     states_equal check when such arguments refine the return value (in this case, set mem_size for     PTR_TO_MEM). The resultant mem_size for the R0 is derived from the constant value, and if the verifier     incorrectly prunes states considering them equivalent where such arguments exist (by seeing that both     registers have reg->precise as false in regsafe), we can end up with invalid programs passing the verifier     which can do access beyond what should have been the correct mem_size in that explored state.

    *)(r1 + 0) 8: r2 = 1 9: if w1 == 0 goto +1 <LBB5_3> 10: r2 = -1 0000000000000058 <LBB5_3>: 11: r1 = 0 ll     13: r3 = 0 14: call bpf_ringbuf_reserve 15: if r0 == 0 goto +7 <LBB5_5> 16: r1 = r0 17: r1 += 16777215 18:
    w2 = 0 19: *(u8 *)(r1 + 0) = r2 20: r1 = r0 21: r2 = 0 22: call bpf_ringbuf_submit 00000000000000b8     <LBB5_5>: 23: w0 = 0 24: exit For the first case, the single line execution's exploration will prune the     search at insn 14 for the branch insn 9's second leg as it will be verified first using r2 = -1     (UINT_MAX), while as w1 at insn 9 will always be 0 so at runtime we don't get error for being greater than     UINT_MAX/4 from bpf_ringbuf_reserve. The verifier during regsafe just sees reg->precise as false for both     r2 registers in both states, hence considers them equal for purposes of states_equal. If we propagated     precise markers using the backtracking support, we would use the precise marking to then ensure that old     r2 (UINT_MAX) was within the new r2 (1) and this would never be true, so the verification would rightfully     fail. The end result is that the out of bounds access at instruction 19 would be permitted without this     fix. Note that reg->precise is always set to true when user does not have CAP_BPF (or when subprog count     is greater than 1 (i.e. use of any static or global functions)), hence this is only a problem when     precision marks need to be explicitly propagated (i.e. privileged users with CAP_BPF). A simplified test     case has been included in the next patch to prevent future regressions. (CVE-2022-49961)

  - A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal information.
    (CVE-2023-2162)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The CentOS Linux 8.4 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.4:CLSA-2026:1792243729 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: 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`.

  - In the Linux kernel, the following vulnerability has been resolved: 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)

  - In the Linux kernel, the following vulnerability has been resolved: 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:

  - In the Linux kernel, the following vulnerability has been resolved: drm/client: Fully protect modes[] with     dev->mode_config.mutex The modes[] array contains pointers to modes on the connectors' mode lists, which     are protected by dev->mode_config.mutex. 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6568 advisory.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.113-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

    Further information about Debian Security Advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://www.debian.org/security/

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - scsi: qla2xxx: Fix use-after-free of qpair work on queue teardown The response queue MSI-X handler     qla2xxx_msix_rsp_q() schedules qla_do_work() via queue_work(ha->wq, &qpair->q_work). qla_do_work()     dereferences the qpair (vha, rsp) and takes qpair->qp_lock. During teardown, qla2xxx_delete_qpair()     deletes the response queue, which calls free_irq() in qla25xx_free_rsp_que(), and then frees the queue and     the qpair. free_irq() waits for running hardirq handlers but does not cancel work already placed on     ha->wq. A still-pending q_work then runs qla_do_work() against the freed qpair and response queue, causing     a use-after-free. This is especially likely during full adapter teardown, where destroy_workqueue(ha->wq)     forces pending work to run after the queue pairs have been freed. Flush the work item with     cancel_work_sync() in qla25xx_free_rsp_que() after free_irq() has released the interrupt (so no new work     can be queued) and before the response queue and qpair memory are freed (so the flushed handler still sees     valid memory).
