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: make sure exp active before
svc_export_show The function `e_show` was called with protection from RCU. This only ensures that `exp`
will not be freed. Therefore, the reference count for `exp` can drop to zero, which will trigger a
refcount use-after-free warning when `exp_get` is called. To resolve this issue, use `cache_get_rcu` to
ensure that `exp` remains active. ------------[ cut here ]------------ refcount_t: addition on 0; use-
