一、漏洞信息
漏洞编号：CVE-2024-54456
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.1.8,6.4.0,6.6.0
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: Fix potential buffer overflowin nfs_sysfs_link_rpc_client()name is char[64] where the size of clnt->cl_program->name remainsunknown. Invoking strcat() directly will also lead to potential bufferoverflow. Change them to strscpy() and strncat() to fix potentialissues.
