Tenable has extracted the preceding description block directly from the EulerOS kernel 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 AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1783791447 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: phy: mdio: fix memory leak Syzbot     reported memory leak in MDIO bus interface, the problem was in wrong state logic. MDIOBUS_ALLOCATED     indicates 2 states: 1. Bus is only allocated 2. Bus allocated and __mdiobus_register() fails, but     device_register() was called In case of device_register() has been called we should call put_device() to     correctly free the memory allocated for this device, but mdiobus_free() calls just kfree(dev) in case of     MDIOBUS_ALLOCATED state To avoid this behaviour we need to set bus->state to MDIOBUS_UNREGISTERED _before_     calling device_register(), because put_device() should be called even in case of device_register()     failure. (CVE-2021-47416)

  - An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

  - In the Linux kernel, the following vulnerability has been resolved: can: isotp: sanitize CAN ID checks in     isotp_bind() Syzbot created an environment that lead to a state machine status that can not be reached     with a compliant CAN ID address configuration. The provided address information consisted of CAN ID     0x6000001 and 0xC28001 which both boil down to 11 bit CAN IDs 0x001 in sending and receiving. Sanitize the     SFF/EFF CAN ID values before performing the address checks. (CVE-2022-49269)

  - In the Linux kernel, the following vulnerability has been resolved: tty: fix deadlock caused by calling     printk() under tty_port->lock pty_write() invokes kmalloc() which may invoke a normal printk() to print     failure message. This can cause a deadlock in the scenario reported by syz-bot below: CPU0 CPU1 CPU2 ----
    ---- ---- lock(console_owner); lock(&port_lock_key); lock(&port->lock); lock(&port_lock_key);
    lock(&port->lock); lock(console_owner); As commit dbdda842fe96 (printk: Add console owner and waiter     logic to load balance console writes) said, such deadlock can be prevented by using printk_deferred() in     kmalloc() (which is invoked in the section guarded by the port->lock). But there are too many printk() on     the kmalloc() path, and kmalloc() can be called from anywhere, so changing printk() to printk_deferred()     is too complicated and inelegant. Therefore, this patch chooses to specify __GFP_NOWARN to kmalloc(), so     that printk() will not be called, and this deadlock problem can be avoided. Syzbot reported the following     lockdep error: ====================================================== WARNING: possible circular locking     dependency detected 5.4.143-00237-g08ccc19a-dirty #10 Not tainted

  - In the Linux kernel, the following vulnerability has been resolved: list: fix a data-race around     ep->rdllist ep_poll() first calls ep_events_available() with no lock held and checks if ep->rdllist is     empty by list_empty_careful(), which reads rdllist->prev. Thus all accesses to it need some protection to     avoid store/load-tearing. Note INIT_LIST_HEAD_RCU() already has the annotation for both prev and next.
    Commit bf3b9f6372c4 (epoll: Add busy poll support to epoll with socket fds.) added the first lockless     ep_events_available(), and commit c5a282e9635e (fs/epoll: reduce the scope of wq lock in epoll_wait())     made some ep_events_available() calls lockless and added single call under a lock, finally commit     e59d3c64cba6 (epoll: eliminate unnecessary lock for zero timeout) made the last ep_events_available()     lockless.

The remote Ubuntu 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8165-1 advisory.

    Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM).
    An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor     profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege     escalation, or possibly escape a container.

    In the Linux kernel, the following vulnerability has been resolved:x86/vmscape: Add conditional IBPB     mitigation

    VMSCAPE is a vulnerability that exploits insufficient branch predictor isolation between a guest and a     userspace hypervisor (like QEMU). Existing mitigations already protect kernel/KVM from a malicious guest.
    Userspace can additionally be protected by flushing the branch predictors after a VMexit.

    Since it is the userspace that consumes the poisoned branch predictors, conditionally issue an IBPB after     a VMexit and before returning to userspace. Workloads that frequently switch between hypervisor and     userspace will incur the most overhead from the new IBPB.

    This new IBPB is not integrated with the existing IBPB sites. For instance, a task can use the existing     speculation control prctl() to get an IBPB at context switch time. With this implementation, the IBPB is     doubled up: one at context switch and another before running userspace. The intent is to integrate and     optimize these cases post-embargo.[ dhansen: elaborate on suboptimal IBPB solution ] (CVE-2025-40300)
