CVE-2026-72341

CVE-2026-72341 affects the Linux kernel net/mlx5e: a publication race in priv->channel_stats[] where mlx5e_channel_stats_alloc() writes channel_stats[ix] before updating stats_nch, without memory barriers. On weakly-ordered architectures (ARM, PowerPC, RISC-V) readers may observe stats_nch == ...

CVE-2026-72072 net/mlx5e: macsec: fix use-after-free of metadata_dst on RX SC delete

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: macsec: fix use-after-free of metadatadst on RX SC delete When an offloaded MACsec RX SC is deleted, macsecdelrxscctx freed the per-SC metadatadst with metadatadstfree, which kfrees the object unconditionally and ignor...

CVE-2026-72072

The CVE-2026-72072 issue affects the Linux kernel MACsec offload path (net/mlx5e) where deleting an offloaded RX SC could lead to use-after-free of metadata_dst. Root cause: metadata_dst was freed unconditionally in macsec_del_rxsc_ctx(), ignoring reference counts, while the RX datapath could sti...
