n the Linux kernel, the following vulnerability has been resolved: exfat: fix the infinite loop in exfat_readdir() If the file system is corrupted so that a cluster is linked to itself in the cluster chain, and there is an unused directory entry in the cluster, 'dentry' will not be incremented, causing condition 'dentry < max_dentries' unable to prevent an infinite loop. This infinite loop causes s_lock not to be released, and other tasks will hang, such as exfat_sync_fs(). This commit stops traversing the cluster chain when there is unused directory entry in the cluster to avoid this infinite loop.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: exfat: se corrige el bucle infinito en exfat_readdir() Si el sistema de archivos está dañado de modo que un clúster está vinculado a sí mismo en la cadena de clústeres y hay una entrada de directorio sin usar en el clúster, 'dentry' no se incrementará, lo que provocará que la condición 'dentry &lt; max_dentries' no pueda evitar un bucle infinito. Este bucle infinito hace que s_lock no se libere y otras tareas se cuelguen, como exfat_sync_fs(). Esta confirmación deja de recorrer la cadena de clústeres cuando hay una entrada de directorio sin usar en el clúster para evitar este bucle infinito.
