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.","published_at":"2026-06-25T08:38:37.521000Z","last_modified_at":null,"cvss_v3_score":7.8,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/c19ff4351214f059349788e13e70e74325831ff6","https://git.kernel.org/stable/c/2b66496d794e98f7aeec7688573051f22ec40bac","https://git.kernel.org/stable/c/98733f3f0becb1ae0701d021c1748e974e5fa55c"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:28.590503Z","updated_at":"2026-06-28T23:30:50.753831Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af","version_start_inclusive":true,"version_end":"c19ff4351214f059349788e13e70e74325831ff6","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af:c19ff4351214f059349788e13e70e74325831ff6"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af","version_start_inclusive":true,"version_end":"2b66496d794e98f7aeec7688573051f22ec40bac","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af:2b66496d794e98f7aeec7688573051f22ec40bac"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af","version_start_inclusive":true,"version_end":"98733f3f0becb1ae0701d021c1748e974e5fa55c","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:fb56fdf8b9a2f7397f8a83dce50189f3f0cf71af:98733f3f0becb1ae0701d021c1748e974e5fa55c"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.13","version_start_inclusive":true,"version_end":"6.13","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.13:6.13"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.13","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.13"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.18.36","version_start_inclusive":true,"version_end":"6.18.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.18.36:6.18.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.0.13","version_start_inclusive":true,"version_end":"7.0.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.0.13:7.0.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.1","version_start_inclusive":true,"version_end":"*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.1:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://git.kernel.org/stable/c/c19ff4351214f059349788e13e70e74325831ff6","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/2b66496d794e98f7aeec7688573051f22ec40bac","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/98733f3f0becb1ae0701d021c1748e974e5fa55c","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-25T08:38:37.521000Z","label":"CVE published","source":null}]}
