ISS X-Force Database: linux-kernel-pppol2tprecvmsg-dos(43111): Linux Kernel pppol2tp

Linux Kernel pppol2tp_recvmsg() denial of service

linux-kernel-pppol2tprecvmsg-dos (43111)

Low Risk

Description:

Linux Kernel is vulnerable to a denial of service, caused by improper bounds checking by the pppol2tp_recvmsg() function. By sending a specially crafted PPP over L2TP packet, a remote attacker from within the local network could exploit this vulnerability to corrupt kernel memory and cause a denial of service.
