CVE-2022-24704 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The rad_packet_recv function in opt/src/accel-pppd/radius/packet.c suffers from a buffer overflow vulnerability, whereby user input len is copied into a fixed buffer &attr->val.integer without any bound checks. If the client connects to the server and sends a large radius packet, a buffer overflow vulnerability will be triggered.. EPSS estimates a 1.16% chance of exploitation in the next 30 days.
