The corruption is triggered during ntfs3 mount-time journal replay of an attacker-supplied NTFS image, delivered via removable media, a loop device, or an image file — there is no network path to `log_replay()`.\nAC:L - Triggering is fully deterministic with no race: the attacker simply sets `sys_page_size`/`page_size` in the $LogFile restart header to a value differing from the host `PAGE_SIZE`, and the stale `page_mask`/`page_bits`/`one_page_buf` mismatch corrupts memory on every mount.\nPR:L - NTFS volumes on removable media are routinely auto-mounted by desktop/kiosk automounters (udisks2) with the in-kernel ntfs3 driver, so an unprivileged local user who supplies the media or image reaches the vulnerable replay path without administrator action.\nUI:N - Automount performs the mount and journal replay automatically when the media is attached; no victim action such as opening a file is required for the overflow to occur.\nS:U - The heap overflow and out-of-bounds reads are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - With a stale mask larger than the new page size, `bytes = log->page_size - page_off` underflows and `memcpy()` reads up to ~4 GiB past `one_page_buf` into the caller's buffer, and the mismatched `page_off`/`bytes` also expose adjacent slab contents to the log parser — an unbounded kernel heap disclosure.\nI:H - When the on-disk page size exceeds the host's, `ntfs_read_run_nb()` writes `log->page_size` bytes (e.g. 64 KiB) of fully attacker-controlled disk data into the 4 KiB `one_page_buf`, a controlled-length, controlled-content linear heap overflow usable for object corruption and control-flow hijack.\nA:H - The commit message documents an outright kernel panic from the negative-length read, and a ~60 KiB slab overwrite or ~4 GiB wild memcpy reliably oopses the machine at mount time." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "fs/ntfs3/fslog.c" ], "versions": [ { "version": "b46acd6a6a627d876898e1c84d3f84902264b445", "lessThan": "0484adcb5fbcadd9ba0fd4485c42630f72e97da9", "status": "affected", "versionType": "git" }, { "version": "b46acd6a6a627d876898e1c84d3f84902264b445", "lessThan": "b90ceffdc975502bc085ce8e79c6adeff05f9521", "status": "affected", "versionType": "git" }, { "version": "b46acd6a6a627d876898e1c84d3f84902264b445", "lessThan": "2cac0df3324b5e287d8020bc0708f7d2dec88a6f", "status": "affected", "versionType": "git" }, { "version": "b46acd6a6a627d876898e1c84d3f84902264b445", "lessThan": "0a4ae2644e2a3b3b219aad9639fb2b0691d08420", "status": "affected", "versionType": "git" }, { "version": "b46acd6a6a627d876898e1c84d3f84902264b445", "lessThan": "2fef55d8f78383c8e6d6d4c014b9597375132696", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "fs/ntfs3/fslog.c" ], "versions": [ { "version": "5.15", "status": "affected" }, { "version": "0", "lessThan": "5.15", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.165", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.103", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.44", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.10.3", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "5.15.165" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.1.103" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.6.44" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.10.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.11" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/0484adcb5fbcadd9ba0fd4485c42630f72e97da9" }, { "url": "https://git.kernel.org/stable/c/b90ceffdc975502bc085ce8e79c6adeff05f9521" }, { "url": "https://git.kernel.org/stable/c/2cac0df3324b5e287d8020bc0708f7d2dec88a6f" }, { "url": "https://git.kernel.org/stable/c/0a4ae2644e2a3b3b219aad9639fb2b0691d08420" }, { "url": "https://git.kernel.org/stable/c/2fef55d8f78383c8e6d6d4c014b9597375132696" } ], "title": "fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-42299", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-09-10T16:10:38.451073Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-12T17:33:28.553Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:03:59.953Z" } } ] } }
