in enterprise/cloud deployments those volumes are commonly accessed remotely through NFS/ksmbd file exports or iSCSI/NVMe-oF/NBD block protocols, letting a remote client drive the vulnerable TAG_CMP path.\nAC:L - An attacker with read access can reliably trigger TAG_CMP by issuing ordinary multi-sector reads; when metadata tag comparisons span dm-bufio buffer boundaries the double-incremented hash_offset mispredicts tag boundaries without races or uncontrollable layout.\nPR:L - Table creation needs CAP_SYS_ADMIN (obtainable in a user namespace), but exploitation only requires read/write access to the mapped block device or an exported filesystem backed by it, not init-namespace root.\nUI:N - Exploitation requires only attacker-initiated reads or writes against the dm-integrity-backed storage; no additional victim actions such as mounting a filesystem or opening files beyond the attacker's own I/O are needed.\nS:U - Impact is incorrect integrity-tag verification within the host kernel's device-mapper layer, enabling undetected data tampering or spurious verification failures on the same host; it does not cross VM, container, or IOMMU security boundaries.\nC:N - The bug corrupts tag-boundary state during comparison but does not cause kernel memory disclosure, out-of-bounds reads, or use-after-free; any wrong data returned is attacker-supplied disk content, not leakage of unrelated kernel or user secrets.\nI:H - Misaligned hash_offset can accept integrity tags that should fail verification (including mixed hash/discard-filler boundaries), defeating dm-integrity's tamper detection and allowing undetected modification of protected block data.\nA:L - The same logic error can spuriously fail checksum verification on legitimate reads, returning I/O errors and denying access to protected data without kernel panic, though repeated reads can sustain a denial-of-service against the volume."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/md/dm-integrity.c"], "versions": [{"version": "84597a44a9d86ac949900441cea7da0af0f2f473", "lessThan": "cf9feed8c131e303ecf2afebe6f791be018818ad", "status": "affected", "versionType": "git"}, {"version": "84597a44a9d86ac949900441cea7da0af0f2f473", "lessThan": "4f4e43337e9ef322595201cfc24def50fd624219", "status": "affected", "versionType": "git"}, {"version": "84597a44a9d86ac949900441cea7da0af0f2f473", "lessThan": "5dfd8042635278613da3b88553e25ade2103cd58", "status": "affected", "versionType": "git"}, {"version": "84597a44a9d86ac949900441cea7da0af0f2f473", "lessThan": "829476c06496aab018f14127c055adb164d1a750", "status": "affected", "versionType": "git"}, {"version": "84597a44a9d86ac949900441cea7da0af0f2f473", "lessThan": "edf025f083854f80032b73a1aad69a3c90db236f", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/md/dm-integrity.c"], "versions": [{"version": "5.7", "status": "affected"}, {"version": "0", "lessThan": "5.7", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.145", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.97", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.40", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.5", "lessThanOrEqual": "7.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2", "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": "5.7", "versionEndExcluding": "6.6.145"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.7", "versionEndExcluding": "6.12.97"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.7", "versionEndExcluding": "6.18.40"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.7", "versionEndExcluding": "7.1.5"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.7", "versionEndExcluding": "7.2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/cf9feed8c131e303ecf2afebe6f791be018818ad"}, {"url": "https://git.kernel.org/stable/c/4f4e43337e9ef322595201cfc24def50fd624219"}, {"url": "https://git.kernel.org/stable/c/5dfd8042635278613da3b88553e25ade2103cd58"}, {"url": "https://git.kernel.org/stable/c/829476c06496aab018f14127c055adb164d1a750"}, {"url": "https://git.kernel.org/stable/c/edf025f083854f80032b73a1aad69a3c90db236f"}], "title": "dm-integrity: don't increment hash_offset twice", "x_generator": {"engine": "bippy-1.2.0"}}}}
