Description OSIDB Bzimport 2025-02-26 03:18:25 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ntfs: add sanity check on allocation size

ntfs_read_inode_mount invokes ntfs_malloc_nofs with zero allocation
size.  It triggers one BUG in the __ntfs_malloc function.

Fix this by adding sanity check on ni->attr_list_size.
