Description
Agostino Sarubbo
![]() CVE-2013-6431 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-6431): The fib6_add function in net/ipv6/ip6_fib.c in the Linux kernel before 3.11.5 does not properly implement error-code encoding, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging the CAP_NET_ADMIN capability for an IPv6 SIOCADDRT ioctl call. Fix in 3.11.5 onwards |
