In the Linux kernel, the following vulnerability has been resolved: net: l2tp: do not propagate multicast notification errors The tunnel create, tunnel modify, session create, and session modify netlink handlers send multicast notifications through helpers that can fail while allocating or encoding a message, or while multicasting it. For tunnel and session create/modify, a notification is sent after the live operation has completed. Returning a best-effort notification error as the command result can therefore report failure for an operation that already committed and can cause callers to retry and accumulate live objects. Keep sending notifications for listener visibility, but do not propagate their best-effort status as the command result. This also keeps the tunnel modify command consistent with the other notification-only paths.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1794643812 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: add HE 6 GHz     capability in the scan elems len The HE 6 GHz Band Capability element is in the probe request for every     band if 6 GHz is supported, so add the size to scan_ies_len. Otherwise, building probe request elements     can fail, triggering the WARN_ON in __ieee80211_start_scan(). (CVE-2026-98328)

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Fix issue in verifying     allow_ptr_leaks After we converted the capabilities of our networking-bpf program from cap_sys_admin to     cap_net_admin+cap_bpf, our networking-bpf program failed to start. Because it failed the bpf verifier, and     the error log is R3 pointer comparison prohibited. A simple reproducer as follows, SEC(cls-ingress)     int ingress(struct __sk_buff *skb) { struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr);
    if ((long)(iph + 1) > (long)skb->data_end) return TC_ACT_STOLEN; return TC_ACT_OK; } Per discussion with     Yonghong and Alexei [1], comparison of two packet pointers is not a pointer leak. This patch fixes it. Our     local kernel is 6.1.y and we expect this fix to be backported to 6.1.y, so stable is CCed. [1].

  - In the Linux kernel, the following vulnerability has been resolved: driver core: Avoid warning when     removing a device while its supplier is unbinding During driver removal, the following warning can appear:
    WARNING: CPU: 1 PID: 139 at drivers/base/core.c:1497 __device_links_no_driver+0xcc/0xfc ... Call trace:
    __device_links_no_driver+0xcc/0xfc (P) device_links_driver_cleanup+0xa8/0xf0     device_release_driver_internal+0x208/0x23c device_links_unbind_consumers+0xe0/0x108     device_release_driver_internal+0xec/0x23c device_links_unbind_consumers+0xe0/0x108     device_release_driver_internal+0xec/0x23c device_links_unbind_consumers+0xe0/0x108     device_release_driver_internal+0xec/0x23c driver_detach+0xa0/0x12c bus_remove_driver+0x6c/0xbc     driver_unregister+0x30/0x60 pci_unregister_driver+0x20/0x9c lan966x_pci_driver_exit+0x18/0xa90     [lan966x_pci] This warning is triggered when a consumer is removed because the links status of its     supplier is not DL_DEV_DRIVER_BOUND and the link flag DL_FLAG_SYNC_STATE_ONLY is not set. The topology in     terms of consumers/suppliers used was the following (consumer ---> supplier): i2c -----------> OIC ---->     PCI device | ^ | | +---> pinctrl ---+ When the PCI device is removed, the OIC (interrupt controller) has     to be removed. In order to remove the OIC, pinctrl and i2c need to be removed and to remove pinctrl, i2c     need to be removed. The removal order is: 1) i2c 2) pinctrl 3) OIC 4) PCI device In details, the removal     sequence is the following (with 0000:01:00.0 the PCI device): driver_detach: call     device_release_driver_internal(0000:01:00.0)... device_links_busy(0000:01:00.0): links->status =     DL_DEV_UNBINDING device_links_unbind_consumers(0000:01:00.0): 0000:01:00.0--oic link->status =     DL_STATE_SUPPLIER_UNBIND call device_release_driver_internal(oic)... device_links_busy(oic): links->status     = DL_DEV_UNBINDING device_links_unbind_consumers(oic): oic--pinctrl link->status =     DL_STATE_SUPPLIER_UNBIND call device_release_driver_internal(pinctrl)... device_links_busy(pinctrl):
    links->status = DL_DEV_UNBINDING device_links_unbind_consumers(pinctrl): pinctrl--i2c link->status =     DL_STATE_SUPPLIER_UNBIND call device_release_driver_internal(i2c)... device_links_busy(i2c): links->status     = DL_DEV_UNBINDING __device_links_no_driver(i2c)... pinctrl--i2c link->status is DL_STATE_SUPPLIER_UNBIND     oic--i2c link->status is DL_STATE_ACTIVE oic--i2c link->supplier->links.status is DL_DEV_UNBINDING The     warning is triggered by the i2c removal because the OIC (supplier) links status is not     DL_DEV_DRIVER_BOUND. Its links status is indeed set to DL_DEV_UNBINDING. It is perfectly legit to have the     links status set to DL_DEV_UNBINDING in that case. Indeed we had started to unbind the OIC which triggered     the consumer unbinding and didn't finish yet when the i2c is unbound. Avoid the warning when the supplier     links status is set to DL_DEV_UNBINDING and thus support this removal sequence without any warnings.
    (CVE-2026-97479)

  - In the Linux kernel, the following vulnerability has been resolved: usb: typec: ucsi: displayport: Fix OOB     altmode array index The UCSI displayport driver indexes the connector's port altmode array with the     GET_CURRENT_CAM response after checking it is not 0xff. The port altmode array is UCSI_MAX_ALTMODES     elements long. If the PPM returns an invalid GET_CURRENT_CAM response above UCSI_MAX_ALTMODES and not     equal to 0xff, the kernel may crash with an array index OOB error. Update the UCSI displayport driver to     verify the current cam is less than UCSI_MAX_ALTMODES before accessing the port altmode array.
    (CVE-2026-90025)

  - In the Linux kernel, the following vulnerability has been resolved: NFSv4.1: fix layout segment leak on     the pnfs_layout_process() forget path When the server returns a new layout stateid while a valid one is     still held, pnfs_layout_process() calls pnfs_mark_matching_lsegs_return() on the on-stack free_me list and     jumps to out_forget. Segments whose reference count drops to zero are unlinked from lo->plh_segs and moved     to free_me by mark_lseg_invalid(); for an idle cached segment the layout header holds the only reference,     so this happens on the first decrement. out_forget never drains free_me -- only the success path calls     pnfs_free_lseg_list(). Commit 814b84971388 (pNFS/NFSv4: Fix a layout segment leak in     pnfs_layout_process()) added the drain; commit 08bd8dbe8882 (pNFS/NFSv4: Try to return invalid layout in     pnfs_layout_process()) removed it while switching the destination to lo->plh_return_segs, which is     drained elsewhere. Commit fb700ef02676 (NFSv4.1: Simplify layout return in pnfs_layout_process())     switched the destination back to free_me without restoring the drain. Restore the pnfs_free_lseg_list()     call. (CVE-2026-89710)

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

An update of the linux package has been released.

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

  - net: l2tp: do not propagate multicast notification errors The tunnel create, tunnel modify, session     create, and session modify netlink handlers send multicast notifications through helpers that can fail     while allocating or encoding a message, or while multicasting it. For tunnel and session create/modify, a     notification is sent after the live operation has completed. Returning a best-effort notification error as     the command result can therefore report failure for an operation that already committed and can cause     callers to retry and accumulate live objects. Keep sending notifications for listener visibility, but do     not propagate their best-effort status as the command result. This also keeps the tunnel modify command     consistent with the other notification-only paths. (CVE-2026-80996)

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