Description

A flaw was found in the Linux kernel's net/mlx5e component. This vulnerability, identified as a "scheduling while atomic" bug, occurs when the mlx5e_ipsec_init_macs() function attempts to query the hardware for a MAC address in an atomic context, which can lead to the system attempting to sleep. A local attacker could potentially trigger this condition, leading to system instability or a kernel panic, resulting in a Denial of Service (DoS).
