Linux Distros Unpatched Vulnerability : CVE-2026-72072

"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 metadatadst on RX SC delete When an offloaded MACsec RX SC is deleted, macsecdelrxscctx freed the per-SC metadatadst...

CVE-2026-72072

A flaw was found in the Linux kernel's MACsec Media Access Control Security component. A race condition during the deletion of an offloaded MACsec RX Security Channel SC allows the RX datapath to access and operate on memory that has already been freed. This use-after-free vulnerability can lead ...

CVE-2026-72019

A flaw was found in the macsec component of the Linux kernel. When processing packets on the AFPACKET SOCKRAW + PACKETQDISCBYPASS transmit path, the macsecencrypt function attempts to read an unset Media Access Control MAC header. This leads to a 12-byte heap over-read, where sensitive data from...

CVE-2026-72072

The CVE-2026-72072 issue affects the Linux kernel’s mlx5e MACsec offload path. A use-after-free could occur when an offloaded MACsec RX SC is deleted: metadata_dst was freed unconditionally via metadata_dst_free(), ignoring the reference count, while readers could attach a freed dst to an skb dur...
