CVE-2007-2480: Linux Kernel

Medium severity, CVSS 4.6. EPSS: 0.4% chance of exploitation in the next 30 days.

The _udp_lib_get_port function in net/ipv4/udp.c in Linux kernel 2.6.21 and earlier does not prevent a bind to a port with a local address when there is already a bind to that port with a wildcard local address, which might allow local users to intercept local traffic for daemons or other applications.

Affected products

• Linux Linux Kernel: up to and including 2.6.21
