Last modified

CVE-2022-24705 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The rad_packet_recv function in radius/packet.c suffers from a memcpy buffer overflow, resulting in an overly-large recvfrom into a fixed buffer that causes a buffer overflow and overwrites arbitrary memory. If the server connects with a malicious client, crafted client requests can remotely trigger this vulnerability.. EPSS estimates a 1.16% chance of exploitation in the next 30 days.
