| CVE-2025-22081 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix a couple integer overflows on 32bit systems On 32bit systems the "off + sizeof(struct NTFS_DE)" addition can have an integer wrapping issue. Fix it by using size_add(). |
| CVE-2025-22080 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Prevent integer overflow in hdr_first_de() The "de_off" and "used" variables come from the disk so they both need to check. The problem is that on 32bit systems if they're both greater than UINT_MAX - 16 then the check does work as intended because of an integer overflow. |
| CVE-2024-52560 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Mark inode as bad as soon as error detected in mi_enum_attr() Extended the `mi_enum_attr()` function interface with an additional parameter, `struct ntfs_inode *ni`, to allow marking the inode as bad as soon as an error is detected. |
| CVE-2024-50248 | In the Linux kernel, the following vulnerability has been resolved: ntfs3: Add bounds checking to mi_enum_attr() Added bounds checking to make sure that every attr don't stray beyond valid memory region. |
| CVE-2024-50247 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Check if more than chunk-size bytes are written A incorrectly formatted chunk may decompress into more than LZNT_CHUNK_SIZE bytes and a index out of bounds will occur in s_max_off. |
| CVE-2024-50246 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Add rough attr alloc_size check |
| CVE-2024-50245 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix possible deadlock in mi_read Mutex lock with another subclass used in ni_lock_dir(). |
| CVE-2024-50244 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Additional check in ni_clear() Checking of NTFS_FLAGS_LOG_REPLAYING added to prevent access to uninitialized bitmap during replay process. |
| CVE-2024-50243 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix general protection fault in run_is_mapped_full Fixed deleating of a non-resident attribute in ntfs_create_inode() rollback. |
| CVE-2024-50242 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Additional check in ntfs_file_release |
| CVE-2024-50065 | In the Linux kernel, the following vulnerability has been resolved: ntfs3: Change to non-blocking allocation in ntfs_d_hash d_hash is done while under "rcu-walk" and should not sleep. __get_name() allocates using GFP_KERNEL, having the possibility to sleep when under memory pressure. Change the allocation to GFP_NOWAIT. |
| CVE-2024-42299 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed If an NTFS file system is mounted to another system with different PAGE_SIZE from the original system, log->page_size will change in log_replay(), but log->page_{mask,bits} don't change correspondingly. This will cause a panic because "u32 bytes = log->page_size - page_off" will get a negative value in the later read_log_page(). |
| CVE-2024-41019 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Validate ff offset This adds sanity checks for ff offset. There is a check on rt->first_free at first, but walking through by ff without any check. If the second ff is a large offset. We may encounter an out-of-bound read. |
| CVE-2024-41018 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Add a check for attr_names and oatbl Added out-of-bound checking for *ane (ATTR_NAME_ENTRY). |
| CVE-2024-38625 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Check 'folio' pointer for NULL It can be NULL if bmap is called. |
| CVE-2024-38624 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Use 64 bit variable to avoid 32 bit overflow For example, in the expression: vbo = 2 * vbo + skip |
| CVE-2024-38623 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Use variable length array instead of fixed size Should fix smatch warning: ntfs_set_label() error: __builtin_memcpy() 'uni->name' too small (20 vs 256) |
| CVE-2024-27407 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fixed overflow check in mi_enum_attr() |
| CVE-2023-52641 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Add NULL ptr dereference checking at the end of attr_allocate_frame() It is preferable to exit through the out: label because internal debugging functions are located there. |
| CVE-2023-52640 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix oob in ntfs_listxattr The length of name cannot exceed the space occupied by ea. |
| CVE-2023-52631 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix an NULL dereference bug The issue here is when this is called from ntfs_load_attr_list(). The "size" comes from le32_to_cpu(attr->res.data_size) so it can't overflow on a 64bit systems but on 32bit systems the "+ 1023" can overflow and the result is zero. This means that the kmalloc will succeed by returning the ZERO_SIZE_PTR and then the memcpy() will crash with an Oops on the next line. |
| CVE-2023-45896 | ntfs3 in the Linux kernel through 6.8.0 allows a physically proximate attacker to read kernel memory by mounting a filesystem (e.g., if a Linux distribution is configured to allow unprivileged mounts of removable media) and then leveraging local access to trigger an out-of-bounds read. A length value can be larger than the amount of memory allocated. NOTE: the supplier's perspective is that there is no vulnerability when an attack requires an attacker-modified filesystem image. |
| CVE-2023-26606 | In the Linux kernel 6.0.8, there is a use-after-free in ntfs_trim_fs in fs/ntfs3/bitmap.c. |
| CVE-2023-26544 | In the Linux kernel 6.0.8, there is a use-after-free in run_unpack in fs/ntfs3/run.c, related to a difference between NTFS sector size and media sector size. |
| CVE-2022-49553 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate BOOT sectors_per_clusters When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a shift value. Make sure that the shift value is not too large before using it (NTFS max cluster size is 2MB). Return -EVINVAL if it too large. This prevents negative shift values and shift values that are larger than the field size. Prevents this UBSAN error: UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16 shift exponent -192 is negative |
| CVE-2022-49550 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: provide block_invalidate_folio to fix memory leak The ntfs3 filesystem lacks the 'invalidate_folio' method and it causes memory leak. If you write to the filesystem and then unmount it, the cached written data are not freed and they are permanently leaked. |
| CVE-2022-48502 | An issue was discovered in the Linux kernel before 6.2. The ntfs3 subsystem does not properly check for correctness during disk reads, leading to an out-of-bounds read in ntfs_set_ea in fs/ntfs3/xattr.c. |
| CVE-2022-48425 | In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT flags before replaying logs. |
| CVE-2022-48424 | In the Linux kernel before 6.1.3, fs/ntfs3/inode.c does not validate the attribute name offset. An unhandled page fault may occur. |
| CVE-2022-48423 | In the Linux kernel before 6.1.3, fs/ntfs3/record.c does not validate resident attribute names. An out-of-bounds write may occur. |
| CVE-2022-4842 | A flaw NULL Pointer Dereference in the Linux kernel NTFS3 driver function attr_punch_hole() was found. A local user could use this flaw to crash the system. |
| CVE-2022-3238 | A double-free flaw was found in the Linux kernel’s NTFS3 subsystem in how a user triggers remount and umount simultaneously. This flaw allows a local user to crash or potentially escalate their privileges on the system. |
| CVE-2022-1973 | A use-after-free flaw was found in the Linux kernel in log_replay in fs/ntfs3/fslog.c in the NTFS journal. This flaw allows a local attacker to crash the system and leads to a kernel information leak problem. |
| CVE-2021-47660 | In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()' All error handling paths lead to 'out' where many resources are freed. Do it as well here instead of a direct return, otherwise 'log', 'ra' and 'log->one_page_buf' (at least) will leak. |
