Even in the removable-media/automount scenario the triggering actions are local syscalls, and Local scores higher than Physical.\nAC:L - The attacker controls both sides of the race (a lookup loop against `mount -o remount,ro`) and can repeat it indefinitely until the window is hit; the `f2fs_readonly()` check in `__recover_dot_dentries()` is checked once with no locking against the remount. Setting the on-disk `F2FS_INLINE_DOTS` bit is trivial and requires no special conditions.\nPR:L - Reaching `f2fs_lookup()` and thus `__recover_dot_dentries()` requires only an unprivileged local account with search access to the mount; the flag arrives from disk via a crafted image or a legacy mkfs.f2fs volume that an automount daemon (Android vold, udisks2) mounts on the attacker's behalf. No capability check exists anywhere on the lookup path.\nUI:N - No victim action is needed \u2014 the attacker performs the lookups, remount and unmount itself, and in the removable-media case the automount daemon mounts the volume without any user interaction.\nS:U - The corruption and the resulting panic/use-after-free are confined to the kernel's own memory and the f2fs superblock structures; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - After the WARN path leaves the evicted inode linked in `sbi->inode_list[DIRTY_META]`, `f2fs_sync_inode_meta()` reads a freed `f2fs_inode_info` via `list_first_entry()` and `igrab()`, giving a use-after-free read of reclaimed slab memory that can be heap-sprayed to disclose kernel data.\nI:H - The same dangling `gdirty_list` entry yields UAF writes through `list_del_init()` in `f2fs_inode_synced()` and `f2fs_update_inode_page()` operating on a reclaimed object, a well-known primitive for heap-spray-based control-flow hijack; the bug additionally leaves persistent on-disk metadata inconsistency requiring fsck.\nA:H - The reported failure is an outright kernel panic at `fs/f2fs/inode.c:896` (`BUG_ON` under CONFIG_F2FS_CHECK_FS, or WARN plus a subsequent use-after-free oops otherwise), triggered on unmount and reproducible on demand."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["fs/f2fs/f2fs.h", "fs/f2fs/namei.c", "include/linux/f2fs_fs.h"], "versions": [{"version": "510022a85839a8409d1e6a519bb86ce71a84f30a", "lessThan": "e8d64f598eeb079c42a52deaa3a91312c736a49d", "status": "affected", "versionType": "git"}, {"version": "510022a85839a8409d1e6a519bb86ce71a84f30a", "lessThan": "f4746f2d79507f65cfbde11d3c39ee8338aa50af", "status": "affected", "versionType": "git"}, {"version": "510022a85839a8409d1e6a519bb86ce71a84f30a", "lessThan": "f9ce2f550d53d044ecfb5ce996406cf42cd6b84d", "status": "affected", "versionType": "git"}, {"version": "510022a85839a8409d1e6a519bb86ce71a84f30a", "lessThan": "8be95cd607478d85fa4626e86f811e785905bcbf", "status": "affected", "versionType": "git"}, {"version": "510022a85839a8409d1e6a519bb86ce71a84f30a", "lessThan": "bcefd0b0611f35b560d0a7281d87529fbe7a1e32", "status": "affected", "versionType": "git"}, {"version": "510022a85839a8409d1e6a519bb86ce71a84f30a", "lessThan": "884ee6dc85b959bc152f15bca80c30f06069e6c4", "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/f2fs/f2fs.h", "fs/f2fs/namei.c", "include/linux/f2fs_fs.h"], "versions": [{"version": "4.1", "status": "affected"}, {"version": "0", "lessThan": "4.1", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.168", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.113", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.54", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.10.13", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.11.2", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12", "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": "4.1", "versionEndExcluding": "5.15.168"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.1", "versionEndExcluding": "6.1.113"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.1", "versionEndExcluding": "6.6.54"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.1", "versionEndExcluding": "6.10.13"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.1", "versionEndExcluding": "6.11.2"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.1", "versionEndExcluding": "6.12"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/e8d64f598eeb079c42a52deaa3a91312c736a49d"}, {"url": "https://git.kernel.org/stable/c/f4746f2d79507f65cfbde11d3c39ee8338aa50af"}, {"url": "https://git.kernel.org/stable/c/f9ce2f550d53d044ecfb5ce996406cf42cd6b84d"}, {"url": "https://git.kernel.org/stable/c/8be95cd607478d85fa4626e86f811e785905bcbf"}, {"url": "https://git.kernel.org/stable/c/bcefd0b0611f35b560d0a7281d87529fbe7a1e32"}, {"url": "https://git.kernel.org/stable/c/884ee6dc85b959bc152f15bca80c30f06069e6c4"}], "title": "f2fs: get rid of online repaire on corrupted directory", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"metrics": [{"other": {"type": "ssvc", "content": {"id": "CVE-2024-47690", "role": "CISA Coordinator", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "version": "2.0.3", "timestamp": "2024-10-21T13:06:03.889382Z"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-10-21T13:14:15.315Z"}}, {"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": "2025-11-03T22:20:55.203Z"}}]}}
