Description
The vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists due to the the failure to consider that the nexthdr field may be associated with an invalid option by the IPv6 fragmentation implementation. A local attacker can use a specially-crafted socket or system call to trigger out-of-bounds read and cause the system to crash.
Successful exploitation of the vulnerability results in denial of service.
