CVE-2026-98929

The Linux kernel contains a vulnerability in the macsec driver where the SecY is initialized after the netdevice is registered. When creating a MACsec device with MAC offload over an LRO-capable lower device, register_netdevice() triggers a NETDEV_FEAT_CHANGE notification before macsec_add_dev() ...

kernel: macsec: fix replay protection at XPN lower-PN wrap

A flaw was found in the Linux kernel's MACsec Media Access Control Security subsystem. When using Extended Packet Numbering XPN, a vulnerability exists where the replay protection mechanism can be bypassed. An attacker can exploit an integer overflow when the packet number reaches its maximum...

Combining Post-Quantum Cryptography and Quantum Key Distribution: Taxonomy, Constructions, Proofs, Standards, Deployments and Open Problems

Post-quantum cryptography PQC and quantum key distribution QKD address the quantum threat from opposite directions: PQC replaces vulnerable public-key algorithms with schemes believed to resist quantum cryptanalysis, while QKD derives keys whose secrecy rests on physical assumptions rather than...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: macsec: Fixed the replay protection issue when pn wraps at U32MAX. In macsecpostdecrypt, when pn is U32MAX, pn + 1 causes an overflow from a 32-bit value to 0. As a result, the first branch never executes. If nextpnhalves.lower i...

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

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 ...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: macsec: Fixed the UAF bug related to realdev. A new macsec device was created, but there was no reference to realdev. This does not ensure that realdev is freed after the macsec device is removed. This will trigger the UAF bug...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: macsec: Fixed the offload support for the NETDEVUNREGISTER event. The current macsec netdev notify handler handles the NETDEVUNREGISTER event by releasing relevant software resources only. This can lead to resource leaks in...
