CVE-2026-74698

A flaw was found in the Linux kernel's net/mlx5e driver. When a Send Queue SQ is re-activated, the Byte Queue Limits BQL counters are incorrectly reset even if there are still network transmissions in progress. This can lead to an inconsistent state, causing the kernel to trigger an error and...

CVE-2026-74698

This vulnerability affects the mlx5e network driver in the Linux kernel (used by Mellanox/NVIDIA ConnectX NICs). The root cause is that mlx5e_activate_txqsq() unconditionally calls netdev_tx_reset_queue(), which zeroes BQL (Byte Queue Limits) counters on channels that still have in-flight TX WQEs...

CVE-2026-72344

A flaw was found in the Linux kernel's net/mlx5e driver. When the mlx5laggetdevseq function encounters an error, such as a peer not being in the Link Aggregation Group LAG or no master device being marked, the system attempts to clean up peer flows without proper validation. This improper handlin...

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. A race condition during the registration of the HV VHCA statistics agent can occur when the agent is published and an asynchronous control invalidation is scheduled before its associated data structures are fully initialized. This timing...
