Descriptions

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

bcachefs: Check for journal entries overruning end of sb clean section

Fix a missing bounds check in superblock validation.

Note that we don't yet have repair code for this case - repair code for
individual items is generally low priority, since the whole superblock
is checksummed, validated prior to write, and we have backups.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bcachefs: comprueba si hay entradas de diario que sobrepasen el final de la sección de limpieza de sb. Corrige una comprobación de límites faltantes en la validación de superbloque. Tenga en cuenta que todavía no tenemos un código de reparación para este caso; el código de reparación para elementos individuales generalmente tiene una prioridad baja, ya que todo el superbloque se suma, se valida antes de escribir y tenemos copias de seguridad.
