Description
In the Linux kernel, the following vulnerability has been resolved:
SUNRPC: fix gss_auth kref leak in gss_alloc_msg error path
Commit 5940d1cf9f42 ("SUNRPC: Rebalance a kref in auth_gss.c") added
a kref_get(&gss_auth->kref) call to balance the gss_put_auth() done
in gss_release_msg(), but forgot to add a corresponding kref_put()
on the error path when kstrdup_const() fails.
If service_name is non-NULL and kstrdup_const() fails, the function
jumps to err_put_pipe_version which calls put_pipe_version() and
kfree(gss_msg), but never releases the gss_auth reference. This leads
to a kref leak where the gss_auth structure is never freed.
Add a forward declaration for gss_free_callback() and call kref_put()
in the err_put_pipe_version error path to properly release the
reference taken earlier.
