By the time calling the cpuhp::teardown() callback the\ncpu_online_mask() hasn't updated yet and still includes the CPU going to\nteardown. In current driver's implementation we may migrate the context\nto the teardown CPU and leads to the below calltrace:\n\n...\n[ 368.104662][ T932] task:cpuhp/0 state:D stack: 0 pid: 15 ppid: 2 flags:0x00000008\n[ 368.113699][ T932] Call trace:\n[ 368.116834][ T932] __switch_to+0x7c/0xbc\n[ 368.120924][ T932] __schedule+0x338/0x6f0\n[ 368.125098][ T932] schedule+0x50/0xe0\n[ 368.128926][ T932] schedule_preempt_disabled+0x18/0x24\n[ 368.134229][ T932] __mutex_lock.constprop.0+0x1d4/0x5dc\n[ 368.139617][ T932] __mutex_lock_slowpath+0x1c/0x30\n[ 368.144573][ T932] mutex_lock+0x50/0x60\n[ 368.148579][ T932] perf_pmu_migrate_context+0x84/0x2b0\n[ 368.153884][ T932] hisi_pcie_pmu_offline_cpu+0x90/0xe0 [hisi_pcie_pmu]\n[ 368.160579][ T932] cpuhp_invoke_callback+0x2a0/0x650\n[ 368.165707][ T932] cpuhp_thread_fun+0xe4/0x190\n[ 368.170316][ T932] smpboot_thread_fn+0x15c/0x1a0\n[ 368.175099][ T932] kthread+0x108/0x13c\n[ 368.179012][ T932] ret_from_fork+0x10/0x18\n...\n\nUse function cpumask_any_but() to find one correct active cpu to fixes\nthis issue."}], "id": "CVE-2023-53656", "lastModified": "2026-11-05T21:17:30.853", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "HIGH", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2023-53656", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2026-11-05T20:26:32.906241Z", "version": "2.0.3"}}]}, "published": "2025-10-07T16:15:49.213", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/7a6a9f1c5a0a875a421db798d4b2ee022dc1ee1a"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/b64569897d86b611befbb895d815280fea94e1ed"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/be9c8c9c84b6d25a7b7d39954030aba6f759feb6"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/f564e543a43d0f1cabac791672c8a6fc78ce12d0"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Analyzed", "weaknesses": [{"description": [{"lang": "en", "value": "NVD-CWE-noinfo"}], "source": "nvd@nist.gov", "type": "Primary"}]}
