CVE-2024-53147
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: exfat: fix out-of-bounds access of directory entries In the case of the directory size is greater than or equal to the cluster size, if start_clu becomes an EOF cluster(an invalid cluster) due to file system corruption, then the directory entry where ei->hint_femp.eidx hint is outside the directory, resulting in an out-of-bounds access, which may cause further file system corruption. This commit adds a check for start_clu, if it is an invalid cluster, the file or directory will be treated as empty.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: exfat: corrige el acceso fuera de los límites de las entradas del directorio. En el caso de que el tamaño del directorio sea mayor o igual al tamaño del clúster, si start_clu se convierte en un clúster EOF (un clúster no válido cluster) debido a una corrupción del sistema de archivos, entonces la entrada del directorio donde ei->hint_femp.eidx sugerencia está fuera del directorio, lo que resulta en un acceso fuera de los límites, lo que puede causar una mayor corrupción del sistema de archivos. Este commit agrega una verificación de start_clu; si es un clúster no válido, el archivo o directorio se tratará como vacío."
