In the Linux kernel, the following vulnerability has been resolved: scsi: imm: Fix use-after-free bug caused by unfinished delayed work The delayed work item 'imm_tq' is initialized in imm_attach() and scheduled via imm_queuecommand() for processing SCSI commands. When the IMM parallel port SCSI host adapter is detached through imm_detach(), the imm_struct device instance is deallocated. However, the delayed work might still be pending or executing when imm_detach() is called, leading to use-after-free bugs when the work function imm_interrupt() accesses the already freed imm_struct memory. The race condition can occur as follows: CPU 0(detach thread) | CPU 1 | imm_queuecommand() | imm_queuecommand_lck() imm_detach() | schedule_delayed_work() kfree(dev) //FREE | imm_interrupt() | dev = container_of(...) //USE dev-> //USE Add disable_delayed_work_sync() in imm_detach() to guarantee proper cancellation of the delayed work item before imm_struct is deallocated.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007420 advisory.

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

    scsi: imm: Fix use-after-free bug caused by unfinished delayed work

    The delayed work item 'imm_tq' is initialized in imm_attach() and     scheduled via imm_queuecommand() for processing SCSI commands.  When the     IMM parallel port SCSI host adapter is detached through imm_detach(),     the imm_struct device instance is deallocated.

    However, the delayed work might still be pending or executing     when imm_detach() is called, leading to use-after-free bugs     when the work function imm_interrupt() accesses the already     freed imm_struct memory.

    The race condition can occur as follows:

    CPU 0(detach thread)   | CPU 1                            | imm_queuecommand()                            |   imm_queuecommand_lck()     imm_detach()           |     schedule_delayed_work()       kfree(dev) //FREE    | imm_interrupt()                            |   dev = container_of(...) //USE                                dev-> //USE

    Add disable_delayed_work_sync() in imm_detach() to guarantee proper     cancellation of the delayed work item before imm_struct is deallocated.

The remote Ubuntu 24.04 LTS / 25.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8094-1 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. (LP: #2143853)

    It was discovered that some AMD Zen 5 processors supporting RDSEED instruction did not properly handle     entropy, potentially resulting in the consumption of insufficiently random values. A local attacker could     possibly use this issue to influence the values returned by the RDSEED instruction causing loss of     confidentiality and integrity. (CVE-2025-62626)

Tenable has extracted the preceding description block directly from the Ubuntu 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - scsi: imm: Fix use-after-free bug caused by unfinished delayed work The delayed work item 'imm_tq' is     initialized in imm_attach() and scheduled via imm_queuecommand() for processing SCSI commands. When the     IMM parallel port SCSI host adapter is detached through imm_detach(), the imm_struct device instance is     deallocated. However, the delayed work might still be pending or executing when imm_detach() is called,     leading to use-after-free bugs when the work function imm_interrupt() accesses the already freed     imm_struct memory. The race condition can occur as follows: CPU 0(detach thread) | CPU 1 |     imm_queuecommand() | imm_queuecommand_lck() imm_detach() | schedule_delayed_work() kfree(dev) //FREE |     imm_interrupt() | dev = container_of(...) //USE dev-> //USE Add disable_delayed_work_sync() in     imm_detach() to guarantee proper cancellation of the delayed work item before imm_struct is deallocated.
    (CVE-2025-68324)

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