A kernel stack flaw that corrupted the Linux kernel’s Mellanox Technologies Spectrum Ethernet driver was found when a user initialized more than 16 access control lists (ACLs). This flaw allows a local user to crash or potentially escalate their privileges on the system.

Mitigation

To mitigate this issue, prevent the mlxsw_spectrum module from being loaded. Please see <https://access.redhat.com/solutions/41278> for information on blacklisting a kernel module to prevent it from loading automatically.
