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"}}]}}
