CVE-2023-53845

CVE-2023-53845 affects the Linux kernel nilfs2 subsystem. When mounting a disk image where a metadata file’s block lookup yields an invalid virtual address, nilfs_bmap_lookup_at_level() could return the same -ENOENT code as a non-existent block, causing nilfs_mdt_get_block() to loop indefinitely ...
