Depending on the relative positions of leaf_cfs_rq_list and\nthe task group (tg) pointer within the struct, this can cause a memory\nfault or access garbage data.\n\nThe issue arises in list_add_leaf_cfs_rq, where both\ncfs_rq->leaf_cfs_rq_list and rq->leaf_cfs_rq_list are added to the same\nleaf list. Also, rq->tmp_alone_branch can be set to rq->leaf_cfs_rq_list.\n\nThis adds a check `if (prev == &rq->leaf_cfs_rq_list)` after the main\nconditional in child_cfs_rq_on_list. This ensures that the container_of\noperation will convert a correct cfs_rq struct.\n\nThis check is sufficient because only cfs_rqs on the same CPU are added\nto the list, so verifying the 'prev' pointer against the current rq's list\nhead is enough.\n\nFixes a potential memory corruption issue that due to current struct\nlayout might not be manifesting as a crash but could lead to unpredictable\nbehavior when the layout changes."}], "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"}, "scenarios": [{"lang": "en", "value": "AV:L - The defect is in core CFS scheduler code (`kernel/sched/fair.c`) reached through ordinary local scheduling activity, cgroup manipulation, and CFS-bandwidth unthrottling; there is no network-facing input path.

No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The type-confused `struct task_group *` is dereferenced at `offsetof(task_group, parent)` from a `list_head` address, which reads out of bounds past the end of the `cfs_rq` slab object into adjacent heap memory whose contents an attacker can influence via heap grooming. This is an unbounded kernel-memory read at an offset determined by struct layout rather than by any bounds check.\nI:H - This is a genuine type confusion \u2014 a `struct rq` list head reinterpreted as a member of `struct cfs_rq`, yielding a fabricated object pointer that is dereferenced \u2014 which upstream explicitly characterizes as \"potential memory corruption.\" Under differing struct layouts the fabricated `tg` pointer is an arbitrary non-pointer value, so the corrupted access is not confined to a benign read.\nA:H - The commit states the invalid conversion \"can cause a memory fault or access garbage data\"; dereferencing a wild `tg` pointer inside the scheduler with the rq lock held produces an oops or panic, and the slab-out-of-bounds read triggers a KASAN report that panics on hardened configurations. A fault in `__update_blocked_fair()` under the runqueue lock is unrecoverable for the affected CPU."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "fdaba61ef8a268d4136d0a113d153f7a89eb9984", "lessThan": "5cb300dcdd27e6a351ac02541e0231261c775852", "versionType": "git"}, {"status": "affected", "version": "fdaba61ef8a268d4136d0a113d153f7a89eb9984", "lessThan": "000c9ee43928f2ce68a156dd40bab7616256f4dd", "versionType": "git"}, {"status": "affected", "version": "fdaba61ef8a268d4136d0a113d153f7a89eb9984", "lessThan": "9cc7f0018609f75a349e42e3aebc3b0e905ba775", "versionType": "git"}, {"status": "affected", "version": "fdaba61ef8a268d4136d0a113d153f7a89eb9984", "lessThan": "b5741e4b9ef3567613b2351384f91d3f16e59986", "versionType": "git"}, {"status": "affected", "version": "fdaba61ef8a268d4136d0a113d153f7a89eb9984", "lessThan": "e1dd09df30ba86716cb2ffab97dc35195c01eb8f", "versionType": "git"}, {"status": "affected", "version": "fdaba61ef8a268d4136d0a113d153f7a89eb9984", "lessThan": "3b4035ddbfc8e4521f85569998a7569668cccf51", "versionType": "git"}], "programFiles": ["kernel/sched/fair.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "5.13"}, {"status": "unaffected", "version": "0", "lessThan": "5.13", "versionType": "semver"}, {"status": "unaffected", "version": "5.15.179", "versionType": "semver", "lessThanOrEqual": "5.15.*"}, {"status": "unaffected", "version": "6.1.131", "versionType": "semver", "lessThanOrEqual": "6.1.*"}, {"status": "unaffected", "version": "6.6.83", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.12.19", "versionType": "semver", "lessThanOrEqual": "6.12.*"}, {"status": "unaffected", "version": "6.13.7", "versionType": "semver", "lessThanOrEqual": "6.13.*"}, {"status": "unaffected", "version": "6.14", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["kernel/sched/fair.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/5cb300dcdd27e6a351ac02541e0231261c775852"}, {"url": "https://git.kernel.org/stable/c/000c9ee43928f2ce68a156dd40bab7616256f4dd"}, {"url": "https://git.kernel.org/stable/c/9cc7f0018609f75a349e42e3aebc3b0e905ba775"}, {"url": "https://git.kernel.org/stable/c/b5741e4b9ef3567613b2351384f91d3f16e59986"}, {"url": "https://git.kernel.org/stable/c/e1dd09df30ba86716cb2ffab97dc35195c01eb8f"}, {"url": "https://git.kernel.org/stable/c/3b4035ddbfc8e4521f85569998a7569668cccf51"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsched/fair: Fix potential memory corruption in child_cfs_rq_on_list\n\nchild_cfs_rq_on_list attempts to convert a 'prev' pointer to a cfs_rq.\nThis 'prev' pointer can originate from struct rq's leaf_cfs_rq_list,\nmaking the conversion invalid and potentially leading to memory\ncorruption.
