Descriptions

In the Linux kernel, the following vulnerability has been resolved:

smb: client: Handle kstrdup failures for passwords

In smb3_reconfigure(), after duplicating ctx->password and
ctx->password2 with kstrdup(), we need to check for allocation
failures.

If ses->password allocation fails, return -ENOMEM.
If ses->password2 allocation fails, free ses->password, set it
to NULL, and return -ENOMEM.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: smb: cliente: Manejar errores de kstrdup para contraseñas. En smb3_reconfigure(), después de duplicar ctx->password y ctx->password2 con kstrdup(), debemos verificar si hay errores de asignación. Si la asignación de ses->password falla, devuelva -ENOMEM. Si la asignación de ses->password2 falla, libere ses->password, configúrelo en NULL y devuelva -ENOMEM.
