一、漏洞信息 漏洞编号：[CVE-2025-38023](https://nvd.nist.gov/vuln/detail/CVE-2025-38023) 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, the following vulnerability has been resolved:nfs: handle failure of nfs_get_lock_context in unlock pathWhen memory is insufficient, the allocation of nfs_lock_context innfs_get_lock_context() fails and returns -ENOMEM. If we mistakenly treatan nfs4_unlockdata structure (whose l_ctx member has been set to -ENOMEM)as valid and proceed to execute rpc_run_task(), this will trigger a NULLpointer dereference in nfs4_locku_prepare.

innfs_get_lock_context() fails and returns -ENOMEM. If we mistakenly treatan nfs4_unlockdata structure (whose l_ctx member has been set to -ENOMEM)as valid and proceed to execute rpc_run_task(), this will trigger a NULLpointer dereference in nfs4_locku_prepare.
