In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: macsec: fix use-after-free of metadata_dst on RX SC delete When an offloaded MACsec RX SC is deleted, macsec_del_rxsc_ctx() freed the per-SC metadata_dst with metadata_dst_free(), which kfree()s the object unconditionally and ignores the dst reference count. The RX datapath in mlx5e_macsec_offload_handle_rx_skb() looks up the SC under rcu_read_lock() via xa_load(), takes a reference with dst_hold() and attaches the dst to the skb with skb_dst_set(). A reader that already obtained the rx_sc pointer can race with the delete path and operate on freed memory. Fix the owner side by dropping the reference with dst_release() instead of freeing unconditionally, and convert the RX datapath to dst_hold_safe() so a reader racing the SC delete cannot attach a dst whose last reference was just dropped; only attach it when a reference was actually taken. mlx5e_macsec_add_rxsc() also published sc_xarray_element via xa_alloc() before rx_sc->md_dst was allocated and initialised, so a datapath reader that looked the SC up by fs_id could observe rx_sc with md_dst still NULL or, on weakly-ordered architectures, a non-NULL md_dst pointer whose contents were not yet visible. NULL-check the xa_load() result and md_dst on the datapath, and reorder add_rxsc() so the xa_alloc() publish happens only after md_dst is fully initialised; the xarray RCU publish then pairs with the rcu_read_lock()/xa_load() in the datapath. Note: macsec_del_rxsc_ctx() also kfree()s rx_sc->sc_xarray_element without an RCU grace period while the same datapath reads it under rcu_read_lock(); that is a separate pre-existing issue left to a follow-up patch.

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

  - net/mlx5e: macsec: fix use-after-free of metadata_dst on RX SC delete When an offloaded MACsec RX SC is     deleted, macsec_del_rxsc_ctx() freed the per-SC metadata_dst with metadata_dst_free(), which kfree()s the     object unconditionally and ignores the dst reference count. The RX datapath in     mlx5e_macsec_offload_handle_rx_skb() looks up the SC under rcu_read_lock() via xa_load(), takes a     reference with dst_hold() and attaches the dst to the skb with skb_dst_set(). A reader that already     obtained the rx_sc pointer can race with the delete path and operate on freed memory. Fix the owner side     by dropping the reference with dst_release() instead of freeing unconditionally, and convert the RX     datapath to dst_hold_safe() so a reader racing the SC delete cannot attach a dst whose last reference was     just dropped; only attach it when a reference was actually taken. mlx5e_macsec_add_rxsc() also published     sc_xarray_element via xa_alloc() before rx_sc->md_dst was allocated and initialised, so a datapath reader     that looked the SC up by fs_id could observe rx_sc with md_dst still NULL or, on weakly-ordered     architectures, a non-NULL md_dst pointer whose contents were not yet visible. NULL-check the xa_load()     result and md_dst on the datapath, and reorder add_rxsc() so the xa_alloc() publish happens only after     md_dst is fully initialised; the xarray RCU publish then pairs with the rcu_read_lock()/xa_load() in the     datapath. Note: macsec_del_rxsc_ctx() also kfree()s rx_sc->sc_xarray_element without an RCU grace period     while the same datapath reads it under rcu_read_lock(); that is a separate pre-existing issue left to a     follow-up patch. Found by 0sec automated security-research tooling (https://0sec.ai). (CVE-2026-72072)

Note that Nessus relies on the presence of the package as reported by the vendor.
