This ties the life cycleof scheduling stats with mm.\nIn account_mm_sched(), the scheduling stats are accessed bytask->mm->sc_stat.  However, a task may be switching mm on one CPU whenanother CPU is running account_mm_sched(), and possibly accessing theold mm that was freed.  This problem was found when running tests withKASAN by Hyunwoo:\n  https://lore.kernel.org/lkml/apPb-Dr4nPYuHQOK@v4bel/\nInstead of serializing the mm access by introducing extra acquisition ofrq lock in the mm free path, extract sched_cache_stat from mm_struct,rename it as sched_cache_group and manage its life cycle apart frommm_struct with its own ref counting.  This allows us in the next patchaccess sched_cache_group directly from task, and add a refcounton sched_cache_group when a task links to it. This prevents the useafter free issue when accessing stale and released old mm and itssched cache stat a task switches to a new mm while account_mm_sched()is done elsewhere.\nThe other benefit of this restructure is in the future, the grouping oftasks to a LLC would have the flexibility to be associated with a userdefined grouping, or cgroup, cookie group, numa_group or others insteadof just with a single mm address space.\nRename sched_cache_stat to sched_cache_group and turn it into a refcountedobject allocated from mm_struct.  The mm_struct now holds a pointer(sched_cache_grp) to this object instead of embedding it.\nhttps://www.cve.org/CVERecord?id=CVE-2026-98385https://git.kernel.org/stable/c/852ecb6bc0bc0106f44f74ba3944524732486025https://git.kernel.org/stable/c/28f9c0e0a0b94c5d3e1b634db545f6e1f94858c5#kernel #Linux#CVE_2026_98385#bot", "url": "https://infosec.exchange/users/cve/statuses/117426436339556597"}, {"timestamp": "2026-10-12T06:17:00Z", "date_only": false, "value": "2026-10-12T06:17:00Z", "kind": "other", "label": "Nvd published at", "source": "github \u00b7 GHSA-984H-V76F-94JC", "record": "GHSA-984H-V76F-94JC", "field": "database_specific.nvd_published_at"}, {"timestamp": "2026-10-12T06:17:00.547Z", "date_only": false, "value": "2026-10-12T06:17:00.547", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-98385", "record": "FKIE_CVE-2026-98385", "field": "published"}, {"timestamp": "2026-10-12T06:17:00.547Z", "date_only": false, "value": "2026-10-12T06:17:00.547", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-98385", "record": "FKIE_CVE-2026-98385", "field": "lastModified"}, {"timestamp": "2026-10-12T06:31:17Z", "date_only": false, "value": "2026-10-12T06:31:17Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-984H-V76F-94JC", "record": "GHSA-984H-V76F-94JC", "field": "published"}, {"timestamp": "2026-10-12T06:31:17Z", "date_only": false, "value": "2026-10-12T06:31:17Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-984H-V76F-94JC", "record": "GHSA-984H-V76F-94JC", "field": "modified"}, {"timestamp": "2026-10-12T06:33:02.115Z", "date_only": false, "value": "2026-10-12T06:33:02.115387Z", "kind": "sighting", "label": "Seen", "source": "https://infosec.exchange/users/vuldb/statuses/117426538525960801", "record": "CVE-2026-98385", "field": "creation_timestamp", "uuid": "b70aadf1-d3e3-42a6-9244-f39e98eddf96", "content": "\u26a0\ufe0f There is a new vulnerability with elevated criticality in Linux Kernel (CVE-2026-98385) https://vuldb.com/vuln/416836", "url": "https://infosec.exchange/users/vuldb/statuses/117426538525960801"}, {"timestamp": "2026-10-13T00:00:00Z", "date_only": false, "value": "2026-10-13T00:00:00Z", "kind": "milestone", "label": "Published", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-98385", "record": "UBUNTU-CVE-2026-98385", "field": "published"}, {"timestamp": "2026-10-13T00:00:00Z", "date_only": false, "value": "2026-10-13T00:00:00Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-98385", "record": "UBUNTU-CVE-2026-98385", "field": "modified"}, {"timestamp": "2026-10-13T06:05:51.365Z", "date_only": false, "value": "2026-10-13T06:05:51.365768Z", "kind": "milestone", "label": "Published", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98385", "record": "BELL-CVE-2026-98385", "field": "published"}, {"timestamp": "2026-10-13T06:25:33.157Z", "date_only": false, "value": "2026-10-13T06:25:33.157590Z", "kind": "other", "label": "Updated", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98385", "record": "BELL-CVE-2026-98385", "field": "modified"}, {"timestamp": "2026-10-13T06:25:33.157Z", "date_only": false, "value": "2026-10-13T06:25:33.157590Z", "kind": "other", "label": "Withdrawn", "source": "osv_bellsoft \u00b7 BELL-CVE-2026-98385", "record": "BELL-CVE-2026-98385", "field": "withdrawn"}]}
