CVE-2023-54077 fs/ntfs3: Fix memory leak if ntfs_read_mft failed

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix memory leak if ntfsreadmft failed Label ATTRROOT in ntfsreadmft sets isroot = true and ni-niflags |= NIFLAGDIR, then next attr will goto label ATTRALLOC and alloc ni-dir.allocrun. However two states are not always...

CVE-2023-54077

CVE-2023-54077 discusses a memory leak in the Linux kernel ntfs3 module (ntfs_read_mft). In ntfs_read_mft, the logic that sets is_root and NI_FLAG_DIR can enter inconsistent states, causing ni->dir.alloc_run to leak when the next attribute flow follows ATTR_ALLOC and NI_FLAG_DIR is not set. Mu...
