CVE-2026-46124

CVE-2026-46124 affects the Linux kernel isofs filesystem. The vulnerability arises because isofs_fh_to_dentry/isofs_fh_to_parent pass an attacker-controlled block number from an NFS file handle to isofs_export_iget(), which only rejects block == 0 before calling isofs_iget and sb_bread. A crafted...
