CVE-2026-89943

High

In the Linux kernel, the following vulnerability has been resolved: ASoC: loongson: Fix error handling in ACPI property parsing In loongson_card_parse_acpi(), the return value of device_property_read_string() for the `codec-dai-name` property was ignored. If the property is missing or invalid, an uninitialized pointer would be used later, potentially leading to undefined behavior. Fix this by checking the return value and propagating the error appropriately.
