In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: TC, Check if flow is PEER before acquiring devcom lock In case mlx5eaddfdbflow fails in lower levels, the flow is deleted via mlx5etcdelflow, and mlx5etcdelflow is acquiring ESW devcom lock without condition. In...
CVE-2026-80739
CVE-2026-80739 affects the Linux kernel 's mlx5_core driver (Mellanox/NVIDIA network hardware), specifically the TC (Traffic Control) offload path in net/mlx5e. When __mlx5e_add_fdb_flow() fails for a peer flow , the cleanup path mlx5e_tc_del_flow() acquires the ESW devcom lock unconditionally wh...

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...
