Vulnerability Title
fs/ntfs3: Initialize allocated memory before use
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Initialize allocated memory before use KMSAN reports: Multiple uninitialized values detected: - KMSAN: uninit-value in ntfs_read_hdr (3) - KMSAN: uninit-value in bcmp (3) Memory is allocated by __getname(), which is a wrapper for kmem_cache_alloc(). This memory is used before being properly cleared. Change kmem_cache_alloc() to kmem_cache_zalloc() to properly allocate and clear memory before use.
