there is no network-facing path to `hfs_write_inode`.\nAC:L - The attacker fully controls the B-tree node offset table that determines `fd.entryoffset`/`fd.entrylength`, so the short-record condition and the out-of-bounds offset are set deterministically in the image; no race or unpredictable state is involved.\nPR:L - A local unprivileged user triggers this by supplying an image that is mounted via the standard removable-media/automount path used to score the other hfs/hfsplus image-parsing CVEs; no elevated capability is needed by the attacker supplying the image.\nUI:N - Once the image is mounted, the vulnerable path executes automatically from generic writeback (dirty inode flush, sync, or umount) with no victim action required.\nS:U - The corruption stays within the kernel's own memory and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `hfs_bnode_read()` copies 70/102 bytes from an attacker-chosen offset past the record and node into a stack union, and that data is subsequently written back into the page cache and reachable through the filesystem, giving out-of-bounds kernel memory disclosure.\nI:H - The unguarded `hfs_bnode_write()` performs a `memcpy_to_page()` of up to 102 bytes at an attacker-controlled offset with no bounds check, yielding an out-of-bounds heap write with partly controlled content — a corruption primitive usable for control-flow hijacking.\nA:H - The same out-of-bounds write reliably corrupts adjacent page-cache/heap memory causing oops or panic, and the unbalanced `hfs_find_init()` error path returns to userspace holding `cat_tree->tree_lock`, permanently deadlocking all further catalog operations on the mount." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "fs/hfs/inode.c" ], "versions": [ { "version": "c886c10a6eddb99923b315f42bf63f448883ef9a", "lessThan": "cc2164ada548addfa8ee215196661c3afe0c5154", "status": "affected", "versionType": "git" }, { "version": "2344f17c0a89c181ab1a9fef57fd8c3bddfd6e30", "lessThan": "82725be426bce0a425cc5e26fbad61ffd29cff03", "status": "affected", "versionType": "git" }, { "version": "90103ccb6e60aa4efe48993d23d6a528472f2233", "lessThan": "da23752d9660ba7a8ca6c5768fd8776f67f59ee7", "status": "affected", "versionType": "git" }, { "version": "4fd3a11804c8877ff11fec59c5c53f1635331e3e", "lessThan": "be01f35efa876eb81cebab2cb0add068b7280ef4", "status": "affected", "versionType": "git" }, { "version": "48d9e2e6de01ed35e965eb549758a837c07b601d", "lessThan": "f10defb0be6ac42fb6a97b45920d32da6bd6fde8", "status": "affected", "versionType": "git" }, { "version": "55d1cbbbb29e6656c662ee8f73ba1fc4777532eb", "lessThan": "90e019006644dad35862cb4aa270f561b0732066", "status": "affected", "versionType": "git" }, { "version": "55d1cbbbb29e6656c662ee8f73ba1fc4777532eb", "lessThan": "45917be9f0af339a45b4619f31c902d37b8aed59", "status": "affected", "versionType": "git" }, { "version": "55d1cbbbb29e6656c662ee8f73ba1fc4777532eb", "lessThan": "cb7a95af78d29442b8294683eca4897544b8ef46", "status": "affected", "versionType": "git" }, { "version": "8c40f2dbae603ef0bd21e87c63f54ec59fd88256", "status": "affected", "versionType": "git" }, { "version": "367296925c7625c3969d2a78d7a3e1dee161beb5", "status": "affected", "versionType": "git" }, { "version": "4.9.337", "lessThan": "4.10", "status": "affected", "versionType": "semver" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "fs/hfs/inode.c" ], "versions": [ { "version": "5.16", "status": "affected" }, { "version": "0", "lessThan": "5.16", "status": "unaffected", "versionType": "semver" }, { "version": "6.0.19", "lessThanOrEqual": "6.0.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.5", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.2", "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": "5.16", "versionEndExcluding": "6.0.19" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.16", "versionEndExcluding": "6.1.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.16", "versionEndExcluding": "6.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.9.337" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/cc2164ada548addfa8ee215196661c3afe0c5154" }, { "url": "https://git.kernel.org/stable/c/82725be426bce0a425cc5e26fbad61ffd29cff03" }, { "url": "https://git.kernel.org/stable/c/da23752d9660ba7a8ca6c5768fd8776f67f59ee7" }, { "url": "https://git.kernel.org/stable/c/be01f35efa876eb81cebab2cb0add068b7280ef4" }, { "url": "https://git.kernel.org/stable/c/f10defb0be6ac42fb6a97b45920d32da6bd6fde8" }, { "url": "https://git.kernel.org/stable/c/90e019006644dad35862cb4aa270f561b0732066" }, { "url": "https://git.kernel.org/stable/c/45917be9f0af339a45b4619f31c902d37b8aed59" }, { "url": "https://git.kernel.org/stable/c/cb7a95af78d29442b8294683eca4897544b8ef46" } ], "title": "hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handling", "x_generator": { "engine": "bippy-1.2.0" } } } }
