In the Linux kernel, the following vulnerability has been resolved: mmc: sunplus: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, 1. the memory allocated in mmc_alloc_host() will be leaked 2. null-ptr-deref will happen when calling mmc_remove_host() in remove function spmmc_drv_remove() because deleting not added device. Fix this by checking the return value of mmc_add_host(). Moreover, I fixed the error handling path of spmmc_drv_probe() to clean up.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-014326 advisory.

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

    mmc: sunplus: fix return value check of mmc_add_host()

    mmc_add_host() may return error, if we ignore its return value,     1. the memory allocated in mmc_alloc_host() will be leaked     2. null-ptr-deref will happen when calling mmc_remove_host()     in remove function spmmc_drv_remove() because deleting not     added device.

    Fix this by checking the return value of mmc_add_host(). Moreover,     I fixed the error handling path of spmmc_drv_probe() to clean up.

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.

  - mmc: sunplus: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its     return value, 1. the memory allocated in mmc_alloc_host() will be leaked 2. null-ptr-deref will happen     when calling mmc_remove_host() in remove function spmmc_drv_remove() because deleting not added device.
    Fix this by checking the return value of mmc_add_host(). Moreover, I fixed the error handling path of     spmmc_drv_probe() to clean up. (CVE-2023-54204)

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