CVE-2026-99078

A flaw was found in the Linux kernel's Mellanox network driver mlx5e. When processing high-speed network traffic using XDP eXpress Data Path sockets under low-memory conditions, a failure during receive queue replenishment can cause previously freed memory buffers to be released again through sta...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix HV VHCA stats zero-sized buffer allocation mlx5ehvvhcastatscreate is called from mlx5enicenable, prior to mlx5eopen. At that point, priv-statsnch remains zero, as it is only incremented in mlx5echannelstatsalloc,...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix HV VHCA stats agent registration race mlx5ehvvhcastatscreate registers the stats agent via mlx5hvvhcaagentcreate. The helper publishes the agent in hvvhca-agentstype under agentslock and immediately schedules an...

CVE-2026-99079

A flaw was found in the Linux kernel's Mellanox network driver mlx5e. When network traffic redirected to an AFXDP eXpress Data Path socket encounters a full receive ring and buffer refills only partially succeed, the driver retains a stale buffer reference. A remote attacker could exploit this...
