This is a reasonable high-impact deployment for Btrfs-backed NAS or server shares.\nAC:L - The attacker can create dirty Btrfs metadata and force commits/syncs through normal file operations; in the highest reasonable scenario, storage/writeback failure can be induced by exhausting thin or shared backing storage. No race or precise memory layout is required.\nPR:N - There is no Btrfs capability check on the vulnerable transaction writeback path, and a remotely writable NFS/SMB export can expose it without local kernel privileges. Choosing the higher-severity case, an accessible writable export/guest-style share requires no privileges on the target host.\nUI:N - Exploitation is driven by attacker-controlled file operations and sync/flush requests. No victim user action is required beyond the system already serving or mounting the Btrfs filesystem.\nS:U - The impact remains within the kernel/filesystem security authority. It does not cross a VM, IOMMU, or sandbox boundary.\nC:N - The bug prematurely drops dirty extent tracking and prevents proper cleanup; it is not a use-after-free, out-of-bounds read, or information disclosure primitive. The investigated impact does not expose kernel or filesystem data to the attacker.\nI:N - The defect does not provide an arbitrary write or controlled data modification primitive. Any failed or late metadata write is part of transaction abort/cleanup behavior rather than attacker-controlled integrity compromise.\nA:H - Leftover dirty extent buffers can later be written back during teardown after workers are stopped, leading to NULL pointer dereferences or kernel warnings/panic conditions. This can crash the kernel or make the filesystem unavailable."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["fs/btrfs/disk-io.c", "fs/btrfs/transaction.c"], "versions": [{"version": "663dfbb07774e0fe1049e8db3054a08500122f18", "lessThan": "ff49321d29770e2d41bec65b43099997af5d2eaa", "status": "affected", "versionType": "git"}, {"version": "663dfbb07774e0fe1049e8db3054a08500122f18", "lessThan": "7107b047e709ad258f7c29a342266a8e3653f370", "status": "affected", "versionType": "git"}, {"version": "663dfbb07774e0fe1049e8db3054a08500122f18", "lessThan": "d915195c2f57794ed8ec4bf131bcead4b5dc29c1", "status": "affected", "versionType": "git"}, {"version": "663dfbb07774e0fe1049e8db3054a08500122f18", "lessThan": "9ebb7eba1237dc198768b9c76506a79f924c82bb", "status": "affected", "versionType": "git"}, {"version": "663dfbb07774e0fe1049e8db3054a08500122f18", "lessThan": "df03d67dc63722845cb9fe59d815d1225b04fd54", "status": "affected", "versionType": "git"}, {"version": "663dfbb07774e0fe1049e8db3054a08500122f18", "lessThan": "4066c55e109475a06d18a1f127c939d551211956", "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/btrfs/disk-io.c", "fs/btrfs/transaction.c"], "versions": [{"version": "3.19", "status": "affected"}, {"version": "0", "lessThan": "3.19", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.191", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.160", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.114", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.33", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.10", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "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": "3.19", "versionEndExcluding": "6.1.191"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.19", "versionEndExcluding": "6.6.160"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.19", "versionEndExcluding": "6.12.114"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.19", "versionEndExcluding": "6.18.33"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.19", "versionEndExcluding": "7.0.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.19", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/ff49321d29770e2d41bec65b43099997af5d2eaa"}, {"url": "https://git.kernel.org/stable/c/7107b047e709ad258f7c29a342266a8e3653f370"}, {"url": "https://git.kernel.org/stable/c/d915195c2f57794ed8ec4bf131bcead4b5dc29c1"}, {"url": "https://git.kernel.org/stable/c/9ebb7eba1237dc198768b9c76506a79f924c82bb"}, {"url": "https://git.kernel.org/stable/c/df03d67dc63722845cb9fe59d815d1225b04fd54"}, {"url": "https://git.kernel.org/stable/c/4066c55e109475a06d18a1f127c939d551211956"}], "title": "btrfs: only release the dirty pages io tree after successful writes", "x_generator": {"engine": "bippy-1.2.0"}}}}
