CVE-2026-46282
iio: frequency: admv1013: fix NULL pointer dereference on str
Description
In the Linux kernel, the following vulnerability has been resolved: iio: frequency: admv1013: fix NULL pointer dereference on str When device_property_read_string() fails, str is left uninitialized but the code falls through to strcmp(str, ...), dereferencing a garbage pointer. Replace manual read/strcmp with device_property_match_property_string() and consolidate the SE mode enums into a single sequential enum, mapping to hardware register values via a switch consistent with other bitfields in the driver. Several cleanup patches have been applied to this driver recently so this will need a manual backport.

Action Type Old Value New Value Added Translation Title: Linux, Description: En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: iio: frequency: admv1013: corrección de desreferencia de puntero NULL en str Cuando device_property_read_string() falla, str queda sin inicializar, pero el código continúa hacia strcmp(str, ...), desreferenciando un puntero basura. Reemplazar la lectura/strcmp manual con device_property_match_property_string() y consolidar las enumeraciones de modo SE en una única enumeración secuencial, mapeando a valores de registro de hardware a través de un switch consistente con otros campos de bits en el controlador. Varios parches de limpieza han sido aplicados a este controlador recientemente, por lo que esto requerirá un backport manual. -
