A vulnerability has been identified in Linux Kernel, which could be exploited by malicious users to cause a denial of service. This issue is caused by memory leak error in the "pppox_unbind_sock()" [drivers/net/pppox.c] function when releasing a connected PPPoE socket before calling the "PPPIOCGCHAN" ioctl, which could be exploited by local attackers to exhaust all available memory resources, creating a denial of service condition.
