Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Change kmem_cache_alloc() to kmem_cache_zalloc() so that allocated memory is properly allocated and cleared before use (addresses KMSAN uninit-value reports in bcmp (3) and ntfs_read_hdr (3), and resolves 'fs/ntfs3: Initialize allocated memory before use').
Linux kernel (KMSAN fix) kmem_cache_alloc() -> kmem_cache_zalloc() = Use kmem_cache_zalloc() instead of kmem_cache_alloc()
