Answer in brief
CVE-2026-46308 records a High severity (CVSS 7.8) vulnerability in pmdomain: mediatek: fix use-after-free in scpsys_get_bus_protection_legacy(). 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 7.8. 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: pmdomain: mediatek: fix use-after-free in scpsys_get_bus_protection_legacy() In scpsys_get_bus_protection_legacy(), of_find_node_with_property() returns a device node with its reference count incremented. The function then calls of_node_put(node) before checking whether syscon_regmap_lookup_by_phandle() returns an error. If an error occurs, dev_err_probe() dereferences the node pointer to print diagnostic information, but the node memory may have already been freed due to the earlier of_node_put(), leading to a use-after-free vulnerability. Fix this by moving the of_node_put() call after the error check, ensuring the node is still valid when accessed in the error path.
