Description

The udp_v6_push_pending_frames function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call.

Affected products

Linux kernel: through 3.10.3; 3.0-rc1, 3.0-rc2, 3.0-rc3, 3.0-rc4, 3.0-rc5, 3.0-rc6 (+241)
