| Description: | Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. Baozeng Ding discovered a use-after-free issue in the generic PPP layer in the Linux kernel. A local attacker could use this to cause a denial of service (system crash).
