CVE-2022-50336 (2022)
In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Add null pointer check to attr_load_runs_vcn

Some metadata files are handled before MFT. This adds a null pointer
check for some corner cases that could lead to NPD while reading these
metadata files for a malformed NTFS image.
