Opened: Nov 02, 2021 Severity: 3-Major
Padding bytes added by TMM to bring packets up to the minimum Ethernet frame length of 64 bytes may contain contents of TMM's CPU memory.
Unintentional leak of TMM memory contents in Ethernet padding on VELOS architecture platforms.
Issue can occur whenever TMM creates a packet that is shorter than the 64 byte Ethernet minimum transmitted on a VELOS architecture platform.
Upgrade to latest BIG-IP version.
Ethernet minimum frame padding explicitly zeroed by TMM's data path driver used on VELOS architecture products.
