CVE-2022-50336 Detail

Description

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.
