CVE-2026-72343

A flaw was found in the net/mlx5e component of the Linux kernel. A zero-sized buffer is allocated during the initialization of HV VHCA statistics. When the hypervisor later attempts to enable statistics reporting, a write operation is performed on this invalid memory address. This can lead to a...

CVE-2026-72342

A flaw was found in the Linux kernel's net/mlx5e component.
