Linux Kernel dccp_feat_change() buffer overflow
| linux-kernel-dccpfeatchange-bo (43034) |  High Risk |
Description:
Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the dccp_feat_change() function within the Datagram Congestion Control Protocol (DCCP) subsystem. By sending a specially-crafted request, a local attacker could overflow a buffer and execute arbitrary code on the system with kernel privileges or cause the application to crash.
