Loading vulnerability…
CVE-2024-26733 is a buffer overflow in the Linux kernel ARP subsystem's arp_req_get() function. When handling the SIOCGARP ioctl, the function copies a neighbour entry's hardware address into arpreq.arp_ha.sa_data, a 14-byte buffer in struct sockaddr, using the network device address length. Addresses longer than the destination can overwrite adjacent fields in struct arpreq. A 16-byte address overwrites arp_flags, while address lengths greater than 22 can overwrite arp_netmask.
