CVE-2026-43498
accel/ivpu: Disallow re-exporting imported GEM objects
Description
In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Disallow re-exporting imported GEM objects Prevent re-exporting of imported GEM buffers by adding a custom prime_handle_to_fd callback that checks if the object is imported and returns -EOPNOTSUPP if so. Re-exporting imported GEM buffers causes loss of buffer flags settings, leading to incorrect device access and data corruption.

Action Type Old Value New Value Added Translation Title: el kernel de Linux, Description: En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: accel/ivpu: Prohibir la reexportación de objetos GEM importados Se evita la reexportación de búferes GEM importados añadiendo una función de devolución de llamada (callback) prime_handle_to_fd personalizada que verifica si el objeto es importado y devuelve -EOPNOTSUPP en ese caso. La reexportación de búferes GEM importados provoca la pérdida de la configuración de los indicadores del búfer, lo que lleva a un acceso incorrecto al dispositivo y a la corrupción de datos. -
