The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990417 advisory.

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

    serial: core: fix transmit-buffer reset and memleak

    Commit 761ed4a94582 (tty: serial_core: convert uart_close to use     tty_port_close) converted serial core to use tty_port_close() but     failed to notice that the transmit buffer still needs to be freed on     final close.

    Not freeing the transmit buffer means that the buffer is no longer     cleared on next open so that any ioctl() waiting for the buffer to drain     might wait indefinitely (e.g. on termios changes) or that stale data can     end up being transmitted in case tx is restarted.

    Furthermore, the buffer of any port that has been opened would leak on     driver unbind.

    Note that the port lock is held when clearing the buffer pointer due to     the ldisc race worked around by commit a5ba1d95e46e (uart: fix race     between uart_put_char() and uart_shutdown()).

    Also note that the tty-port shutdown() callback is not called for     console ports so it is not strictly necessary to free the buffer page     after releasing the lock (cf. d72402145ace (tty/serial: do not free     trasnmit buffer page under port lock)).

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 version of kernel installed on the remote host is prior to 4.14.262-200.489. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1749 advisory.

    A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was     found in the way users call some interrupts with high frequency from one of the guests.A local user could     use this flaw to starve the resources resulting in a denial of service. (CVE-2021-28711)

(CVE-2021-28713)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: The timeout could even never trigger if the guest manages to have only one free     slot in its RX queue ring page and the next package would require more than one free slot, which may be     the case when using GSO, XDP, or software hashing. (CVE-2021-28714)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715)

    A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a     privileged local account can leak kernel stack information when issuing commands to the     /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it     can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

    A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    (CVE-2021-4083)

    A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size     increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS     filesystem otherwise not accessible to them. (CVE-2021-4155)

    A use-after-free flaw in the Linux kernel TEE (Trusted Execution Environment) subsystem was found in the     way user calls ioctl TEE_IOC_OPEN_SESSION or TEE_IOC_INVOKE. A local user could use this flaw to crash the     system or escalate their privileges on the system. If the Linux system non configured with the     CONFIG_PREEMPT option or CONFIG_CPU_SW_DOMAIN_PAN option enabled, then it is unlikely that a user can     trigger this issue. (CVE-2021-44733)
