This opens a window where a concurrent list_lru_del() arriving\nfor the dying memcg sees xa_load() == NULL, walks to the parent in\nlock_list_lru_of_memcg(), takes the parent's per-node lock, and calls\nlist_del_init() on an item still physically linked on the dying memcg's\nlist.\n\nIf another in-flight thread holds the dying memcg's per-node lock at the\nsame moment (another list_lru_del, or a list_lru_walk_one running an\nisolate callback), both threads modify ->next/->prev pointers on the same\nphysical list under different locks. Adjacent items can corrupt each\nother's links.\n\nFix it by reversing the order: reparent each per-node list and mark the\nchild's list lru dead and then clear the xarray entry. Any concurrent\nlist_lru op that finds the still-set xarray entry either takes the dying\nmemcg's per-node lock (synchronizing with the drain) or sees LONG_MIN and\nwalks to the parent, where the items now live."}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.8, "baseSeverity": "HIGH"}}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["mm/list_lru.c"], "versions": [{"version": "fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af", "lessThan": "c19ff4351214f059349788e13e70e74325831ff6", "status": "affected", "versionType": "git"}, {"version": "fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af", "lessThan": "2b66496d794e98f7aeec7688573051f22ec40bac", "status": "affected", "versionType": "git"}, {"version": "fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af", "lessThan": "98733f3f0becb1ae0701d021c1748e974e5fa55c", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["mm/list_lru.c"], "versions": [{"version": "6.13", "status": "affected"}, {"version": "0", "lessThan": "6.13", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.36", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.13", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "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": "6.13", "versionEndExcluding": "6.18.36"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.0.13"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.13", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/c19ff4351214f059349788e13e70e74325831ff6"}, {"url": "https://git.kernel.org/stable/c/2b66496d794e98f7aeec7688573051f22ec40bac"}, {"url": "https://git.kernel.org/stable/c/98733f3f0becb1ae0701d021c1748e974e5fa55c"}], "title": "mm/list_lru: drain before clearing xarray entry on reparent", "x_generator": {"engine": "bippy-1.2.0"}}}}
