CVE-2022-3621

A flaw was found in the NILFS2 file system implementation in the Linux kernel. If the imode field in inode of the metadata files is corrupted on the disk, it can cause the initialization of the bmap structure not being called, resulting in a NULL pointer dereference at nilfsbmaplookupatlevel. A...

CVE-2022-3649

A flaw was found in the NILFS2 file system implementation in the Linux kernel. If the beginning of the inode bitmap area was corrupted on disk, an inode with the same inode number as the root inode could be allocated and fail soon after. The subsequent call to nilfsclearinode wrongly decremented...
