Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> fs/ntfs3: Initialize allocated memory before use<br /> <br /> KMSAN reports: Multiple uninitialized values detected:<br /> <br /> - KMSAN: uninit-value in ntfs_read_hdr (3)<br /> - KMSAN: uninit-value in bcmp (3)<br /> <br /> Memory is allocated by __getname(), which is a wrapper for<br /> kmem_cache_alloc().
