CVE-2023-52900

A vulnerability was found in the Linux kernel's nilfs2 file system where improper sanitization checks can result in a general protection fault caused by how the nilfs_btree_insert() function interprets a return value (-ENOENT) from the __nilfs_btree_get_block() function. This return value is used to indicate that a read was attempted against an invalid virtual block address. However, this return value is the same as the internal code that b-tree lookup routines return to indicate that a block being searched does not exist. When nilfs_btree_insert() receives this code from nilfs_btree_do_lookup(), it misinterprets the check as successful and continues the insert operation using the incomplete lookup path, causing the issue. This vulnerability potentially leads to data corruption or system instability.
