A vulnerability in the Linux kernel's IPv4 UDP handling allowed off-path attackers to perform a side-channel attack on the FIB nexthop exception (FNHE) cache to discover ephemeral UDP port numbers. The issue arises because FNHE entries were only created when a UDP packet matched an existing socket, enabling attackers to infer port information by observing cache behavior. Previous mitigations involving hash randomization were bypassable. The fix ensures FNHE entries are always created before socket matching, preventing attackers from distinguishing valid from invalid guesses based on cache state.
