If no task can bebalanced to dst_cpu we ll try to balance the task to the new_dst_cpuinstead. In this case when the migration disabled task is not on CPU itonly allows to run on its current CPU, load balance will select itscurrent CPU as new_dst_cpu and later triggers the warning above.The new_dst_cpu is chosen from the env->dst_grpmask. Currently itcontains CPUs in sched_group_span() and if we have overlapped groups it spossible to run into this case. This patch makes env->dst_grpmask ofgroup_balance_mask() which exclude any CPUs from the busiest group andsolve the issue. For balancing in a domain with no overlapped groupsthe behaviour keeps same as before. 漏洞公开时间：2025-09-15 23:15:48 漏洞创建时间：2025-09-16 00:11:32 漏洞详情参考链接： https://nvd.nist.gov/vuln/detail/CVE-2023-53215

running CPU.This is because that on load balance if the dst_cpu is not allowed by thetask, we ll re-select a new_dst_cpu as a candidate. If no task can bebalanced to dst_cpu we ll try to balance the task to the new_dst_cpuinstead. In this case when the migration disabled task is not on CPU itonly allows to run on its current CPU, load balance will select itscurrent CPU as new_dst_cpu and later triggers the warning above.The new_dst_cpu is chosen from the env->dst_grpmask. Currently itcontains CPUs in sched_group_span() and if we have overlapped groups it spossible to run into this case. This patch makes env->dst_grpmask ofgroup_balance_mask() which exclude any CPUs from the busiest group andsolve the issue. For balancing in a domain with no overlapped groupsthe behaviour keeps same as before.The Linux kernel CVE team has assigned CVE-2023-53215 to this issue. openEuler评分： 5.5 Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H 受影响版本排查(受影响/不受影响)： 1.openEuler-20.03-LTS-SP4(4.19.90):受影响 2.master(6.12.33):不受影响 3.openEuler-22.03-LTS-SP3(5.10.0):不受影响 4.openEuler-22.03-LTS-SP4(5.10.0):不受影响 5.openEuler-24.03-LTS(6.6.0):不受影响 6.openEuler-24.03-LTS-Next(6.6.0):不受影响 7.openEuler-24.03-LTS-SP1(6.6.0):不受影响 8.openEuler-24.03-LTS-SP2(6.6.0):不受影响 修复是否涉及abi变化(是/否)： 1.master(6.12.33):否 2.openEuler-20.03-LTS-SP4(4.19.90):否 3.openEuler-22.03-LTS-SP3(5.10.0):否 4.openEuler-22.03-LTS-SP4(5.10.0):否 5.openEuler-24.03-LTS(6.6.0):否 6.openEuler-24.03-LTS-Next(6.6.0):否 7.openEuler-24.03-LTS-SP1(6.6.0):否 8.openEuler-24.03-LTS-SP2(6.6.0):否 原因说明： 1.openEuler-20.03-LTS-SP4(4.19.90):正常修复 2.master(6.12.33):不受影响-漏洞代码不能被攻击者触发 3.openEuler-22.03-LTS-SP3(5.10.0):不受影响-漏洞代码不能被攻击者触发 4.openEuler-22.03-LTS-SP4(5.10.0):不受影响-漏洞代码不能被攻击者触发 5.openEuler-24.03-LTS(6.6.0):不受影响-漏洞代码不能被攻击者触发 6.openEuler-24.03-LTS-Next(6.6.0):不受影响-漏洞代码不能被攻击者触发 7.openEuler-24.03-LTS-SP1(6.6.0):不受影响-漏洞代码不能被攻击者触发 8.openEuler-24.03-LTS-SP2(6.6.0):不受影响-漏洞代码不能被攻击者触发 三、漏洞修复 安全公告链接：https://www.openeuler.org/zh/security/safety-bulletin/detail/?id=openEuler-SA-2025-2406

__secondary_switched+0xb0/0xb4 ---[ end trace 0000000000000000 ]---Further investigation shows that the warning is superfluous, the migrationdisabled task is just going to be migrated to its current running CPU.This is because that on load balance if the dst_cpu is not allowed by thetask, we ll re-select a new_dst_cpu as a candidate. If no task can bebalanced to dst_cpu we ll try to balance the task to the new_dst_cpuinstead. In this case when the migration disabled task is not on CPU itonly allows to run on its current CPU, load balance will select itscurrent CPU as new_dst_cpu and later triggers the warning above.The new_dst_cpu is chosen from the env->dst_grpmask. Currently itcontains CPUs in sched_group_span() and if we have overlapped groups it spossible to run into this case. This patch makes env->dst_grpmask ofgroup_balance_mask() which exclude any CPUs from the busiest group andsolve the issue. For balancing in a domain with no overlapped groupsthe behaviour keeps same as before.The Linux kernel CVE team has assigned CVE-2023-53215 to this issue. openEuler评分： 5.5 Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H 受影响版本排查(受影响/不受影响)： 1.openEuler-20.03-LTS-SP4(4.19.90):受影响 2.master(6.12.33):不受影响 3.openEuler-22.03-LTS-SP3(5.10.0):不受影响 4.openEuler-22.03-LTS-SP4(5.10.0):不受影响 5.openEuler-24.03-LTS(6.6.0):不受影响 6.openEuler-24.03-LTS-Next(6.6.0):不受影响 7.openEuler-24.03-LTS-SP1(6.6.0):不受影响 8.openEuler-24.03-LTS-SP2(6.6.0):不受影响 修复是否涉及abi变化(是/否)： 1.master(6.12.33):否 2.openEuler-20.03-LTS-SP4(4.19.90):否 3.openEuler-22.03-LTS-SP3(5.10.0):否 4.openEuler-22.03-LTS-SP4(5.10.0):否 5.openEuler-24.03-LTS(6.6.0):否 6.openEuler-24.03-LTS-Next(6.6.0):否 7.openEuler-24.03-LTS-SP1(6.6.0):否 8.openEuler-24.03-LTS-SP2(6.6.0):否 原因说明： 1.openEuler-20.03-LTS-SP4(4.19.90):正常修复 2.master(6.12.33):不受影响-漏洞代码不能被攻击者触发 3.openEuler-22.03-LTS-SP3(5.10.0):不受影响-漏洞代码不能被攻击者触发 4.openEuler-22.03-LTS-SP4(5.10.0):不受影响-漏洞代码不能被攻击者触发 5.openEuler-24.03-LTS(6.6.0):不受影响-漏洞代码不能被攻击者触发 6.openEuler-24.03-LTS-Next(6.6.0):不受影响-漏洞代码不能被攻击者触发 7.openEuler-24.03-LTS-SP1(6.6.0):不受影响-漏洞代码不能被攻击者触发 8.openEuler-24.03-LTS-SP2(6.6.0):不受影响-漏洞代码不能被攻击者触发 三、漏洞修复 安全公告链接：https://www.openeuler.org/zh/security/safety-bulletin/detail/?id=openEuler-SA-2025-2406
