CVE-2025-71114
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: via_wdt: fix critical boot hang due to unnamed resource allocation The VIA watchdog driver uses allocate_resource() to reserve a MMIO region for the watchdog control register. However, the allocated resource was not given a name, which causes the kernel resource tree to contain an entry marked as "<BAD>" under /proc/iomem on x86 platforms. During boot, this unnamed resource can lead to a critical hang because subsequent resource lookups and conflict checks fail to handle the invalid entry properly.

"value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nvia_wdt: corrige un cuelgue crítico de arranque debido a la asignación de recursos sin nombre\n\nEl controlador de watchdog de VIA utiliza allocate_resource() para reservar una región MMIO para el registro de control del watchdog. Sin embargo, al recurso asignado no se le dio un nombre, lo que provoca que el árbol de recursos del kernel contenga una entrada marcada como '' bajo /proc/iomem en plataformas x86.\n\nDurante el arranque, este recurso sin nombre puede provocar un cuelgue crítico porque las búsquedas de recursos y las comprobaciones de conflictos posteriores no logran manejar la entrada inválida correctamente."
