Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: nfsd: Fix cred ref leak in
 nfsd_nl_threads_set_doit(). syzbot reported memory leak of struct cred. [0] nfsd_nl_threads_set_doit()
 passes get_current_cred() to nfsd_svc(), but put_cred() is not called after that. The cred is finally
 passed down to _svc_xprt_create(), which calls get_cred() with the cred for struct svc_xprt. The ownership
 of the refcount by get_current_cred() is not transferred to anywhere and is just leaked. nfsd_svc() is
 also called from write_threads(), but it does not bump file->f_cred there. nfsd_nl_threads_set_doit() is
 called from sendmsg() and current->cred does not go away. Let's use current_cred() in
 nfsd_nl_threads_set_doit(). [0]: BUG: memory leak unreferenced object 0xffff888108b89480 (size 184): comm
