Denial of service in the Linux kernel flow dissector allows remote attackers to trigger an unaligned access exception by sending crafted PPPoE Protocol Field Compression (PFC) frames to an Ethernet interface on alignment-sensitive architectures such as MIPS. The flaw affects kernels from 6.0 onward where Receive Packet Steering (RPS) or similar features invoke the flow dissector on incoming frames, and no PPPoE session needs to be active on the targeted interface. EPSS is very low (0.02%) and there is no public exploit identified at time of analysis, but the vendor has released patched kernel versions.
A denial of service vulnerability (CVSS 7.5). High severity vulnerability requiring prompt remediation.
