CVE-2026-99241 Nov 2, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
ntfs: take invalidate_lock in ntfs_filemap_page_mkwrite()
ntfs_filemap_page_mkwrite() calls iomap_page_mkwrite() without holding
mapping->invalidate_lock, so a concurrent truncate or fallocate can be
in the middle of invalidating pagecache and rewriting the runlist while
the write fault maps blocks and dirties the folio. This races with
ntfs_attr_fallocate(), which merges clusters into the in-memory
runlist, drops the runlist
