Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm: nv04: Fix out of bounds access

When Output Resource (dcb->or) value is assigned in
fabricate_dcb_output(), there may be out of bounds access to
dac_users array in case dcb->or is zero because ffs(dcb->or) is
used as index there.
The 'or' argument of fabricate_dcb_output() must be interpreted as a
number of bit to set, not value.

Utilize macros from 'enum nouveau_or' in calls instead of hardcoding.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm: nv04: corregir el acceso fuera de los límites Cuando se asigna el valor del recurso de salida (dcb->or) en fabricate_dcb_output(), puede haber acceso fuera de los límites a la matriz dac_users en caso de que dcb->or es cero porque ffs(dcb->or) se usa como índice allí. El argumento 'o' de fabricate_dcb_output() debe interpretarse como un número de bits a configurar, no como un valor. Utilice macros de 'enum nouveau_or' en las llamadas en lugar de codificarlas. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.
