Description OSIDB Bzimport 2025-02-27 03:02:33 UTC 
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 remains
unknown. Invoking strcat() directly will also lead to potential buffer
overflow. Change them to strscpy() and strncat() to fix potential
issues.
