CVE-2026-64210

A flaw was found in the Linux kernel's mlx5e driver, which manages Mellanox network adapters. This vulnerability occurs during network processing when CPU core assignments change, leading to a race condition where critical data structures (ICOSQ - Interrupt Coalescing Send Queue) can be updated without proper synchronization. A remote attacker could potentially exploit this timing issue to cause system instability or a kernel crash, resulting in a denial of service (DoS).
