    Changed Description In the Linux kernel, the following vulnerability has been resolved: ext4: sanity check for NULL pointer after ext4_force_shutdown Test case: 2 threads write short inline data to a file. In ext4_page_mkwrite the resulting inline data is converted. Handling ext4_grp_locked_error with description "block bitmap and bg descriptor inconsistent: X vs Y free clusters" calls ext4_force_shutdown. The conversion clears EXT4_STATE_MAY_INLINE_DATA but fails for ext4_destroy_inline_data_nolock and ext4_mark_iloc_dirty due to ext4_forced_shutdown. The restoration of inline data fails for the same reason not setting EXT4_STATE_MAY_INLINE_DATA. Without the flag set a regular process path in ext4_da_write_end follows trying to dereference page folio private pointer that has not been set. The fix calls early return with -EIO error shall the pointer to private be NULL.

    Removed Translation Title: kernel de Linux Description: En el kernel de Linux, se resolvió la siguiente vulnerabilidad: ext4: verificación de integridad del puntero NULL después de ext4_force_shutdown Caso de prueba: 2 subprocesos escriben datos breves en línea en un archivo. En ext4_page_mkwrite se convierten los datos en línea resultantes. El manejo de ext4_grp_locked_error con la descripción "mapa de bits de bloque y descriptor de bg inconsistentes: clústeres libres X vs Y" llama a ext4_force_shutdown. La conversión borra EXT4_STATE_MAY_INLINE_DATA pero falla para ext4_destroy_inline_data_nolock y ext4_mark_iloc_dirty debido a ext4_forced_shutdown. La restauración de datos en línea falla por el mismo motivo al no configurar EXT4_STATE_MAY_INLINE_DATA. Sin el indicador establecido, una ruta de proceso normal en ext4_da_write_end sigue intentando eliminar la referencia al puntero privado de la página que no se ha configurado. La solución llama al retorno anticipado con el error -EIO y el puntero a privado será NULL.
