CVE-2026-90420

CVE-2026-90420 affects the nilfs2 filesystem in the Linux kernel. The vulnerability is an infinite loop in nilfs_clean_segments(): when nilfs_segctor_construct() repeatedly returns -EROFS (for example, after a device is remounted read-only following an I/O error), the cleaner thread logs the erro...
