  3. CVE-2024-54456
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.

Summary
  • (es) En el núcleo de Linux, se ha resuelto la siguiente vulnerabilidad: NFS: Se solucionó un posible desbordamiento de búfer en nfs_sysfs_link_rpc_client() cuyo nombre es char[64], donde el tamaño de clnt->cl_program->name sigue siendo desconocido. Invocar strcat() directamente también provocará un posible desbordamiento de búfer. Cámbielos a strscpy() y strncat() para solucionar posibles problemas.
