The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989765 advisory.

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

    io_uring: lock overflowing for IOPOLL

    syzbot reports an issue with overflow filling for IOPOLL:

    There is no real problem for normal IOPOLL as flush is also called with     uring_lock taken, but it's getting more complicated for IOPOLL|SQPOLL,     for which __io_cqring_overflow_flush() happens from the CQ waiting path.

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

Note that Nessus has not tested for this issue 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.

    In the Linux kernel, the following vulnerability has been resolved:iommu: Return right value in     iommu_sva_bind_device()  iommu_sva_bind_device() should return either a sva bond handle or an ERR_PTR     value in error cases. Existing drivers (idxd and uacce) only check the return value with IS_ERR(). This     could potentially lead to a kernel NULL pointer dereference issue if the function returns NULL instead of     an error pointer.  In reality, this doesn't cause any problems because iommu_sva_bind_device() only     returns NULL when the kernel is not configured with CONFIG_IOMMU_SVA. In this case,     iommu_dev_enable_feature(dev, IOMMU_DEV_FEAT_SVA) will return an error, and the device drivers won't call     iommu_sva_bind_device() at all.(CVE-2024-40945)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986662 advisory.

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

    io_uring: lock overflowing for IOPOLL

    syzbot reports an issue with overflow filling for IOPOLL:

    There is no real problem for normal IOPOLL as flush is also called with     uring_lock taken, but it's getting more complicated for IOPOLL|SQPOLL,     for which __io_cqring_overflow_flush() happens from the CQ waiting path.

The version of kernel installed on the remote host is prior to 5.10.165-143.735. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-026 advisory.

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

    hfs: fix OOB Read in __hfs_brec_find (CVE-2022-50581)

    The Linux kernel does not correctly mitigate SMT attacks, as discovered through a strange pattern in the     kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a     syscall. The kernel also does not issue an IBPB immediately during the syscall. (CVE-2023-0045)

    A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could     allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to     the root user via arbitrary code execution. (CVE-2023-0179)

    There is a logic error in io_uring's implementation which can be used to trigger a use-after-free     vulnerability leading to privilege escalation. In the io_prep_async_work function the assumption that the     last io_grab_identity call cannot return false is not true, and in this case the function will use the     init_cred or the previous linked requests identity to do operations instead of using the current identity.
    This can lead to reference counting issues causing use-after-free. We recommend upgrading past version     5.10.161. (CVE-2023-0240)

    A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network     subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

    Detected a few exploitable gadgets that could leak secret memory through a side-channel such as MDS as     well as insufficient hardening of the usercopy functions against spectre-v1. (CVE-2023-0459)

    There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local     privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or     CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege.

    There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock.

    When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket.
    The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is     created from the listener, the context is inherited and vulnerable.

    The setsockopt TCP_ULP operation does not require any privilege.

    We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

    In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows     an unprivileged user to trigger a denial of service (system crash) via a crafted traffic control     configuration that is set up with tc qdisc and tc class commands.
