CVE-2026-72345

A flaw was found in the Linux kernel's mlx5 LAG Link Aggregation Group driver. An off-by-one error in the mlx5lagcreatesinglefdb function's error rollback mechanism can lead to operations on uninitialized memory or a double-free condition. This could result in system instability or a denial of...

CVE-2026-72341

A flaw was found in the Linux kernel's net/mlx5e component. A local attacker could exploit a race condition during the publication of channel statistics. On weakly-ordered architectures, this could lead to a null pointer dereference, causing a system crash and a denial of service...

CVE-2026-72006

A flaw was found in the Linux kernel's mlx5 driver. Repeated allocation and release of mkeys with TPH steering-tag hints can cause a memory leak of struct mlx5stidxdata. This unreferenced memory accumulates over time, potentially leading to resource exhaustion and a Denial of Service DoS for...

The vulnerability of the functions mlx5e_tc_del_fdb_peer_flow() and mlx5e_tc_clean_fdb_peer_flows() in the driver module drivers/net/ethernet/mellanox/mlx5/core/en_tc.c of the Mellanox Ethernet network adapter driver for the Linux operating system, which allows a hacker to cause a service failure.

The vulnerability of the functions mlx5etcdelfdbpeerflow and mlx5etccleanfdbpeerflows in the driver module drivers/net/ethernet/mellanox/mlx5/core/entc.c of the Mellanox Ethernet network adapter driver for the Linux operating system is related to pointer manipulation. Exploiting this vulnerabilit...
