The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-582.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix memleak of     nhc_pcpu_rth_output in fib_check_nh_v6_gw(). fib_check_nh_v6_gw() expects that fib6_nh_init() cleans up     everything when it fails. Commit 7dd73168e273 (ipv6: Always allocate pcpu memory in a fib6_nh) moved     fib_nh_common_init() before alloc_percpu_gfp() within fib6_nh_init() but forgot to add cleanup for     fib6_nh->nh_common.nhc_pcpu_rth_output in case it fails to allocate fib6_nh->rt6i_pcpu, resulting in     memleak. Let's call fib_nh_common_release() and clear nhc_pcpu_rth_output in the error path. Note that we     can remove the fib6_nh_release() call in nh_create_ipv6() later in net-next.git. (CVE-2025-22005)

  - In the Linux kernel, the following vulnerability has been resolved: igb: Fix potential invalid memory     access in igb_init_module() The pci_register_driver() can fail and when this happened, the dca_notifier     needs to be unregistered, otherwise the dca_notifier can be called when igb fails to install, resulting to     invalid memory access. (CVE-2024-52332)

  - In the Linux kernel, the following vulnerability has been resolved: nfsd: release svc_expkey/svc_export     with rcu_work The last reference for `cache_head` can be reduced to zero in `c_show` and `e_show`(using     `rcu_read_lock` and `rcu_read_unlock`). Consequently, `svc_export_put` and `expkey_put` will be invoked,     leading to two issues: 1. The `svc_export_put` will directly free ex_uuid. However, `e_show`/`c_show` will     access `ex_uuid` after `cache_put`, which can trigger a use-after-free issue, shown below.

This approach allows for an asynchronous context to invoke     `path_put` and also facilitates the freeing of `uuid/exp/key` after an RCU grace period. (CVE-2024-53216)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx5: Fix implicit ODP use after     free Prevent double queueing of implicit ODP mr destroy work by using __xa_cmpxchg() to make sure this is     the only time we are destroying this specific mr. Without this change, we could try to invalidate this mr     twice, which in turn could result in queuing a MR work destroy twice, and eventually the second work could     execute after the MR was freed due to the first work, causing a user after free and trace below.
