CVE-2026-63890

A flaw was found in the Linux kernel's Fibre Channel over Ethernet FCoE module. An unauthenticated attacker on the same Layer 2 L2 network segment could send a specially crafted FCoE Initialization Protocol FIP frame with a malformed descriptor. This could lead to an infinite loop, causing a deni...

CVE-2026-63889

A flaw was found in the Linux kernel's Fibre Channel FC transport component. An adjacent Fibre Channel fabric actor, such as a compromised switch or fabric controller, can send a specially crafted FPIN ELS Fabric Performance Incentive Notification Extended Link Service frame. This malformed frame...
