In the Linux kernel, the following vulnerability has been resolved: mtd: slram: remove failed entries from the device list register_device() links a new slram_mtdlist entry before allocating all of the state needed by the entry. If a later allocation, memremap(), or mtd_device_register() fails, the partially initialized entry remains on the global list. A later cleanup can then dereference or free invalid state from that failed entry. Unwind the partially initialized entry and clear the list tail on each failure path after the entry has been linked.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-104545 advisory.

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

    mtd: slram: remove failed entries from the device list

    register_device() links a new slram_mtdlist entry before allocating all     of the state needed by the entry. If a later allocation, memremap(), or     mtd_device_register() fails, the partially initialized entry remains on     the global list. A later cleanup can then dereference or free invalid     state from that failed entry.

    Unwind the partially initialized entry and clear the list tail on each     failure path after the entry has been linked.

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.

  - mtd: slram: remove failed entries from the device list register_device() links a new slram_mtdlist entry     before allocating all of the state needed by the entry. If a later allocation, memremap(), or     mtd_device_register() fails, the partially initialized entry remains on the global list. A later cleanup     can then dereference or free invalid state from that failed entry. Unwind the partially initialized entry     and clear the list tail on each failure path after the entry has been linked. (CVE-2026-72171)

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

An update of the linux package has been released.
