The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986306 advisory.

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

    scsi: core: Fix bad pointer dereference when ehandler kthread is invalid

    Commit 66a834d09293 (scsi: core: Fix error handling of scsi_host_alloc())     changed the allocation logic to call put_device() to perform host cleanup     with the assumption that IDA removal and stopping the kthread would     properly be performed in scsi_host_dev_release(). However, in the unlikely     case that the error handler thread fails to spawn, shost->ehandler is set     to ERR_PTR(-ENOMEM).

    The error handler cleanup code in scsi_host_dev_release() will call     kthread_stop() if shost->ehandler != NULL which will always be the case     whether the kthread was successfully spawned or not. In the case that it     failed to spawn this has the nasty side effect of trying to dereference an     invalid pointer when kthread_stop() is called. The following splat provides     an example of this behavior in the wild:

The version of kernel installed on the remote host is prior to 5.4.141-67.229. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-006 advisory.

    A flaw was found in the Linux kernel. This flaw allows attackers to cause a denial of service (soft     lockup) by triggering the destruction of a large SEV VM, which requires unregistering many encrypted     regions. The highest threat from this vulnerability is to system availability. (CVE-2020-36311)

    In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because     of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a     side-channel attack, aka CID-9183671af6db. (CVE-2021-33624)

    A flaw in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel in the eBPF subsystem (CVE-2021-35477)

    A vulnerability was found in the Linux kernel. Missing size validations on inbound SCTP packets may allow     the kernel to read uninitialized memory. (CVE-2021-3655)

    A lack of CPU resources in the Linux kernel tracing module functionality was found in the way users use     the trace ring buffer in specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could     use this flaw to starve the resources causing denial of service. (CVE-2021-3679)

    ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

    A flaw was found in the Linux kernel, where it incorrectly computes the access permissions of a shadow     page. This issue leads to a missing guest protection page fault. (CVE-2021-38198)

    A flaw was found in the hanging of mounts in the Linux kernel's NFS4 subsystem where remote servers are     unreachable for the client during migration of data from one server to another (during trunking     detection). This flaw allows a remote NFS4 server (if the client is connected) to starve the resources,     causing a denial of service. The highest threat from this vulnerability is to system availability.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986351 advisory.

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

    scsi: core: Fix bad pointer dereference when ehandler kthread is invalid

    Commit 66a834d09293 (scsi: core: Fix error handling of scsi_host_alloc())     changed the allocation logic to call put_device() to perform host cleanup     with the assumption that IDA removal and stopping the kthread would     properly be performed in scsi_host_dev_release(). However, in the unlikely     case that the error handler thread fails to spawn, shost->ehandler is set     to ERR_PTR(-ENOMEM).

    The error handler cleanup code in scsi_host_dev_release() will call     kthread_stop() if shost->ehandler != NULL which will always be the case     whether the kthread was successfully spawned or not. In the case that it     failed to spawn this has the nasty side effect of trying to dereference an     invalid pointer when kthread_stop() is called. The following splat provides     an example of this behavior in the wild:

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

    scsi: core: Fix bad pointer dereference when ehandler kthread is invalid

    Commit 66a834d09293 (scsi: core: Fix error handling of scsi_host_alloc())     changed the allocation logic to call put_device() to perform host cleanup     with the assumption that IDA removal and stopping the kthread would     properly be performed in scsi_host_dev_release(). However, in the unlikely     case that the error handler thread fails to spawn, shost->ehandler is set     to ERR_PTR(-ENOMEM).

    The error handler cleanup code in scsi_host_dev_release() will call     kthread_stop() if shost->ehandler != NULL which will always be the case     whether the kthread was successfully spawned or not. In the case that it     failed to spawn this has the nasty side effect of trying to dereference an     invalid pointer when kthread_stop() is called. The following splat provides     an example of this behavior in the wild:

The version of kernel installed on the remote host is prior to 4.14.241-184.433. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1696 advisory.

    A flaw was found in the Linux kernel, where a BPF program can obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel attack. This issue occurs when the protection mechanism     neglects the possibility of uninitialized memory locations on the BPF stack. The highest threat from this     vulnerability is to confidentiality. (CVE-2021-34556)

    A flaw in the Linux kernel allows a privileged BPF program to obtain sensitive information from kernel     memory via a Speculative Store Bypass side-channel in the eBPF subsystem (CVE-2021-35477)
