Descriptions
In the Linux kernel, the following vulnerability has been resolved:
f2fs: compress: fix to cover normal cluster write with cp_rwsem
When we overwrite compressed cluster w/ normal cluster, we should
not unlock cp_rwsem during f2fs_write_raw_pages(), otherwise data
will be corrupted if partial blocks were persisted before CP & SPOR,
due to cluster metadata wasn't updated atomically.
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.
