CVE-2026-68461CVE-2026-68461
Description
In the Linux kernel, the following vulnerability has been resolved:
device property: initialize the remaining fields of fwnode_handle 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 uninitialized 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. While at it: initialize the remaining fields of struct
fwnode_handle too just to be sure.
