Description OSIDB Bzimport 2024-11-05 18:03:08 UTC 
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.
