There is no network-facing consumer of this path.\nAC:L - With an fd held open across a forced remount-ro (mount -o remount,ro,force or SysRq emergency remount) the trigger is deterministic, and the remount,nointegrity path in jfs_reconfigure() tears down the log with no SB_RDONLY set and no writer hold-off, leaving a multi-second window an attacker can hammer with a write loop. No memory-layout or victim-state condition outside the attacker's influence is needed.\nPR:L - The memory-unsafe operation executes in the context of an ordinary unprivileged process's buffered write on a JFS file; the read-only/log-teardown transition is a routine system event (shutdown remount, emergency remount, integrity-flag remount, removable-media handling) rather than something the attacker must supply. Basic local user access with a writable fd on a JFS volume suffices.\nUI:N - No victim action is required \u2014 the attacker's own write(2) call drives the entire path through xtTruncate() and txEnd(0). The filesystem is already mounted in the targeted deployment scenario.\nS:U - The wild-pointer read/write, lock corruption and filesystem metadata damage all occur within the kernel's own security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - txEnd(0) dereferences TxBlock[0].sb, which is uninitialized vmalloc memory holding stale kernel data, and then chases it a second time (JFS_SBI(tblk->sb)->log), while TXN_WAKEUP walks an uninitialized wait_queue_head's garbage list pointers. This uninitialized-memory-driven corruption is groomable and leverageable for kernel memory disclosure.\nI:H - Without the fix, xtTruncate() runs with COMMIT_PWMAP and mutates xtree metadata and the persistent block map of a filesystem that must not be modified \u2014 the fix exists precisely so that \"no further data modification will occur\". Additionally, `--log->active` performs a decrement write through a pointer derived from uninitialized memory, and TxAnchor.freetid is corrupted to 0 so later transactions reuse the uninitialized TxBlock[0].\nA:H - The immediate observed result is a kernel oops (\"BUG: unable to handle kernel paging request\"/null-ptr-deref) in txEnd(). It occurs while the global TXN_LOCK spinlock, the inode commit_mutex and IWRITE_LOCK are held, so the locks are never released and every subsequent JFS operation on the system deadlocks."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["fs/jfs/inode.c"], "versions": [{"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "b98506e61e1bb6764c6711198cfab826df8ca952", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "1fee021d6cf1d41b3f6e3fd028939be8f5d5c5db", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "b57a8983916fc2cf54fd8de3afc733c6b3d1c0e5", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "41da1715cd24e177678f93ee27f737b095fc838b", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "77038187890ea82d237b05c8a9c4e08a38b1efcb", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "f605bc3e162f5c6faa9bd3602ce496053d06a4bb", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "b5799dd77054c1ec49b0088b006c9908e256843b", "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/jfs/inode.c"], "versions": [{"version": "2.6.12", "status": "affected"}, {"version": "0", "lessThan": "2.6.12", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.269", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.220", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.187", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.156", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.108", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.14.2", "lessThanOrEqual": "6.14.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.15", "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": "2.6.12", "versionEndExcluding": "5.10.269"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "5.15.220"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.1.187"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.6.156"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.12.108"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.14.2"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.15"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/b98506e61e1bb6764c6711198cfab826df8ca952"}, {"url": "https://git.kernel.org/stable/c/1fee021d6cf1d41b3f6e3fd028939be8f5d5c5db"}, {"url": "https://git.kernel.org/stable/c/b57a8983916fc2cf54fd8de3afc733c6b3d1c0e5"}, {"url": "https://git.kernel.org/stable/c/41da1715cd24e177678f93ee27f737b095fc838b"}, {"url": "https://git.kernel.org/stable/c/77038187890ea82d237b05c8a9c4e08a38b1efcb"}, {"url": "https://git.kernel.org/stable/c/f605bc3e162f5c6faa9bd3602ce496053d06a4bb"}, {"url": "https://git.kernel.org/stable/c/b5799dd77054c1ec49b0088b006c9908e256843b"}], "title": "jfs: add check read-only before truncation in jfs_truncate_nolock()", "x_generator": {"engine": "bippy-1.2.0"}}}}
