Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: f2fs: compress: corrección para cubrir la escritura normal del clúster con cp_rwsem Cuando sobrescribimos el clúster comprimido con el clúster normal, no debemos desbloquear cp_rwsem durante f2fs_write_raw_pages(); de lo contrario, los datos se dañarán si Los bloques parciales persistieron antes de CP y SPOR, debido a que los metadatos del clúster no se actualizaron atómicamente.
