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.

Severity ?
