Answer in brief
CVE-2026-46288 records a High severity (CVSS 8.4) vulnerability in of: unittest: fix use-after-free in of_unittest_changeset(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: of: unittest: fix use-after-free in of_unittest_changeset() The variable 'parent' is assigned the value of 'nchangeset' earlier in the function, meaning both point to the same struct device_node. The call to of_node_put(nchangeset) can decrement the reference count to zero and free the node if there are no other holders. After that, the code still uses 'parent' to check for the presence of a property and to read a string property, leading to a use-after-free. Fix this by moving the of_node_put() call after the last access to 'parent', avoiding the UAF.
