CVE-2025-71271

In the Linux kernel, the following vulnerability has been resolved: hfsplus: ensure sb->s_fs_info is always cleaned up When hfsplus was converted to the new mount api a bug was introduced by changing the allocation pattern of sb->s_fs_info. If setup_bdev_super() fails after a new superblock has been allocated by sget_fc(), but before hfsplus_fill_super() takes ownership of the filesystem-specific s_fs_info data it was leaked. Fix this by freeing sb->s_fs_info in hfsplus_kill_super().

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: hfsplus: asegurar que sb -> s_fs_info siempre se limpie Cuando hfsplus fue convertido a la nueva API de montaje, se introdujo un error al cambiar el patrón de asignación de sb -> s_fs_info. Si setup_bdev_super() falla después de que un nuevo superbloque ha sido asignado por sget_fc(), pero antes de que hfsplus_fill_super() tome posesión de los datos s_fs_info específicos del sistema de archivos, se filtraba. Solucione esto liberando sb -> s_fs_info en hfsplus_kill_super().
