CVE-2026-98833
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
mtd: core: llamar a _get_device() con el MTD maestro
__get_mtd_device() llama al callback _get_device() del maestro con mtd, que puede ser una partición. __put_mtd_device() pasa el maestro.
Esto rompe las particiones gluebi porque gluebi_get_device() usa container_of() y por lo tanto requiere el MTD maestro. Pasar el maestro a _get_device(), coincidiendo con _put_device().
