一、漏洞信息 漏洞编号：[CVE-2025-38305](https://nvd.nist.gov/vuln/detail/CVE-2025-38305) 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel) 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.4.0,6.6.0 CVSS V3.0分值： BaseScore：N/A None Vector：CVSS：3.0/ 漏洞简述： In the Linux kernel, a recursive locking issue was identified in the ptp_vclock_in_use() function. When reading ptp->n_vclocks through ptp->n_vclocks_mux, it triggers a recursive lock call chain starting from n_vclocks_store(), leading to a potential deadlock. The root cause is the redundant check for ptp->n_vclocks in ptp_vclock_in_use(), as other functions already ensure ptp->n_vclocks is checked before unregistering vclocks. 漏洞公开时间：2025-07-10 16:15:29

ptp->n_vclocks check logic in ptp_vclock_in_use()There is no disagreement that we should check both ptp->is_virtual_clockand ptp->n_vclocks to check if the ptp virtual clock is in use.However, when we acquire ptp->n_vclocks_mux to read ptp->n_vclocks inptp_vclock_in_use(), we observe a recursive lock in the call tracestarting from n_vclocks_store().============================================WARNING: possible recursive locking detected6.15.0-rc6 #1 Not tainted--------------------------------------------syz.0.1540/13807 is

***....============================================The best way to solve this is to remove the logic that checksptp->n_vclocks in ptp_vclock_in_use().The reason why this is appropriate is that any path that usesptp->n_vclocks must unconditionally check if ptp->n_vclocks is greaterthan 0 before unregistering vclocks, and all functions are alreadywritten this way. And in the function that uses ptp->n_vclocks, wealready get ptp->n_vclocks_mux before unregistering vclocks.Therefore, we need to remove the redundant check for ptp->n_vclocks inptp_vclock_in_use() to prevent recursive locking.The Linux kernel CVE team has assigned CVE-2025-38305 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-24.03-LTS(6.6.0):受影响 2.openEuler-24.03-LTS-SP1(6.6.0):受影响 3.openEuler-24.03-LTS-SP2(6.6.0):受影响 4.master(6.12.33):不受影响 5.openEuler-20.03-LTS-SP4(4.19.90):不受影响 6.openEuler-22.03-LTS-SP3(5.10.0):不受影响 7.openEuler-22.03-LTS-SP4(5.10.0):不受影响 8.openEuler-24.03-LTS-Next(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-24.03-LTS(6.6.0):正常修复 2.openEuler-24.03-LTS-SP1(6.6.0):正常修复 3.openEuler-24.03-LTS-SP2(6.6.0):正常修复 4.master(6.12.33):不受影响-漏洞代码不能被攻击者触发 5.openEuler-24.03-LTS-Next(6.6.0):不受影响-漏洞代码不能被攻击者触发 6.openEuler-20.03-LTS-SP4(4.19.90):不受影响-漏洞代码不存在 7.openEuler-22.03-LTS-SP3(5.10.0):不受影响-漏洞代码不存在 8.openEuler-22.03-LTS-SP4(5.10.0):不受影响-漏洞代码不存在

ptp->n_vclocks check logic in ptp_vclock_in_use()There is no disagreement that we should check both ptp->is_virtual_clockand ptp->n_vclocks to check if the ptp virtual clock is in use.However, when we acquire ptp->n_vclocks_mux to read ptp->n_vclocks inptp_vclock_in_use(), we observe a recursive lock in the call tracestarting from n_vclocks_store().============================================WARNING: possible recursive locking detected6.15.0-rc6 #1 Not tainted--------------------------------------------syz.0.1540/13807 is trying to acquire lock:ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: ptp_vclock_in_use drivers/ptp/ptp_private.h:103 [inline]ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: ptp_clock_unregister+0x21/0x250 drivers/ptp/ptp_clock.c:415but task is already holding lock:ffff888030704868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at: n_vclocks_store+0xf1/0x6d0 drivers/ptp/ptp_sysfs.c:215other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&ptp->n_vclocks_mux); lock(&ptp->n_vclocks_mux); *** DEADLOCK ***....============================================The best way to solve this is to remove the logic that checksptp->n_vclocks in ptp_vclock_in_use().The reason why this is appropriate is that any path that usesptp->n_vclocks must unconditionally check if ptp->n_vclocks is greaterthan 0 before unregistering vclocks, and all functions are alreadywritten this way. And in the function that uses ptp->n_vclocks, wealready get ptp->n_vclocks_mux before unregistering vclocks.Therefore, we need to remove the redundant check for ptp->n_vclocks inptp_vclock_in_use() to prevent recursive locking.The Linux kernel CVE team has assigned CVE-2025-38305 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-24.03-LTS(6.6.0):受影响 2.openEuler-24.03-LTS-SP1(6.6.0):受影响 3.openEuler-24.03-LTS-SP2(6.6.0):受影响 4.master(6.12.33):不受影响 5.openEuler-20.03-LTS-SP4(4.19.90):不受影响 6.openEuler-22.03-LTS-SP3(5.10.0):不受影响 7.openEuler-22.03-LTS-SP4(5.10.0):不受影响 8.openEuler-24.03-LTS-Next(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-24.03-LTS(6.6.0):正常修复 2.openEuler-24.03-LTS-SP1(6.6.0):正常修复 3.openEuler-24.03-LTS-SP2(6.6.0):正常修复 4.master(6.12.33):不受影响-漏洞代码不能被攻击者触发 5.openEuler-24.03-LTS-Next(6.6.0):不受影响-漏洞代码不能被攻击者触发 6.openEuler-20.03-LTS-SP4(4.19.90):不受影响-漏洞代码不存在 7.openEuler-22.03-LTS-SP3(5.10.0):不受影响-漏洞代码不存在 8.openEuler-22.03-LTS-SP4(5.10.0):不受影响-漏洞代码不存在
