In the Linux kernel, the following vulnerability has been resolved: device property: set fwnode->secondary to NULL in fwnode_init() If a firmware node is allocated on the stack (for instance: temporary software node whose life-time we control) or on the heap - but using a non-zeroing allocation function - and initialized using fwnode_init(), its secondary pointer will contain uninitalized memory which likely will be neither NULL nor IS_ERR() and so may end up being dereferenced (for example: in dev_to_swnode()). Set fwnode->secondary to NULL on initialization.

An update of the linux package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - device property: set fwnode->secondary to NULL in fwnode_init() If a firmware node is allocated on the     stack (for instance: temporary software node whose life-time we control) or on the heap - but using a non-     zeroing allocation function - and initialized using fwnode_init(), its secondary pointer will contain     uninitalized memory which likely will be neither NULL nor IS_ERR() and so may end up being dereferenced     (for example: in dev_to_swnode()). Set fwnode->secondary to NULL on initialization. (CVE-2026-64220)

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