Vulnerability from cvelistv5

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: libceph: remove debugfs files before client teardown ceph_destroy_client() tears down the monitor client before removing the per-client debugfs files. A concurrent read of the monmap debugfs file can enter monmap_show() after ceph_monc_stop() has freed monc->monmap, triggering a use-after-free. Remove the debugfs files before stopping the OSD and monitor clients. debugfs_remove() drains active handlers and prevents new accesses, so the debugfs callbacks can no longer race the rest of client teardown.

a local attacker can independently issue debugfs reads and trigger or time against client teardown without requiring another user to click, open files, or mount filesystems.\\nS:U - The use-after-free corrupts kernel heap memory within the same kernel security domain and does not cross VM, container, or IOMMU boundaries; impact is standard kernel privilege escalation or crash.\\nC:H - The use-after-free on monc-\u003emonmap permits reading freed heap memory containing monitor addresses and entity metadata, and UAF primitives are routinely leveraged for arbitrary kernel memory disclosure.\\nI:H - Heap use-after-free on the variable-length ceph_monmap structure enables memory corruption that can be groomed into arbitrary kernel write primitives and local privilege escalation via control-flow hijacking.\\nA:H - Concurrent access to freed monmap memory during debugfs iteration can cause kernel oops, BUG, or panic, and UAF corruption reliably threatens system availability even when full exploitation is not attempted.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"ac78549d186090ee7125d28c3a8c376573b36194\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"463a264e9094384112a5c8b46f0a9ddaf8566904\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"fe46b7e06f14f6f94766832df309b249cb689d27\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"fc1010e7e0204ece6cc0f9af4f473e9553535eab\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"d3dc8889d39a676bf840132bd5c5c48cb0daba23\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"8f5a3abc54ba24dbceb14cc3a719908c4f688091\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"b9fedda2f628e030384228de0dafc574b7fb0c2f\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"76aa844d5b2fb8c839180d3f5874e333b297e5fd\", \"lessThan\": \"e4c804726c4afce3ba648b982d564f6af2cfa328\", \"versionType\": \"git\"}], \"programFiles\": [\"net/ceph/ceph_common.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"2.6.34\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"2.6.34\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"5.10.265\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.15.216\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.15.*\"}, {\"status\": \"unaffected\", \"version\": \"6.1.183\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.1.*\"}, {\"status\": \"unaffected\", \"version\": \"6.6.148\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.6.*\"}, {\"status\": \"unaffected\", \"version\": \"6.12.101\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.12.*\"}, {\"status\": \"unaffected\", \"version\": \"6.18.42\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"6.18.*\"}, {\"status\": \"unaffected\", \"version\": \"7.1.6\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"7.1.*\"}, {\"status\": \"unaffected\", \"version\": \"7.2\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/ceph/ceph_common.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/ac78549d186090ee7125d28c3a8c376573b36194\"}, {\"url\": \"https://git.kernel.org/stable/c/463a264e9094384112a5c8b46f0a9ddaf8566904\"}, {\"url\": \"https://git.kernel.org/stable/c/fe46b7e06f14f6f94766832df309b249cb689d27\"}, {\"url\": \"https://git.kernel.org/stable/c/fc1010e7e0204ece6cc0f9af4f473e9553535eab\"}, {\"url\": \"https://git.kernel.org/stable/c/d3dc8889d39a676bf840132bd5c5c48cb0daba23\"}, {\"url\": \"https://git.kernel.org/stable/c/8f5a3abc54ba24dbceb14cc3a719908c4f688091\"}, {\"url\": \"https://git.kernel.org/stable/c/b9fedda2f628e030384228de0dafc574b7fb0c2f\"}, {\"url\": \"https://git.kernel.org/stable/c/e4c804726c4afce3ba648b982d564f6af2cfa328\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nlibceph: remove debugfs files before client teardown\\n\\nceph_destroy_client() tears down the monitor client before removing\\nthe per-client debugfs files.
