CVE-2026-98141Hinoki check available

Silent symlink creation failure via ignored index error

Published Sep 25, 2026 · Updated Sep 25, 2026

Error handling in the Linux kernel NTFS reparse-data path in 7.1 allows local users to receive false success for failed symlink creation. update_reparse_data() discards the return value from set_reparse_index(), removes newly written reparse data after an insertion failure, and still returns success. Reachability requires an NTFS volume and an index-insertion failure; the result is an absent symlink or WSL special file rather than code execution or data disclosure.
