2.1/10

Summary

ulp/sdp/sdp_proc.c in the ib_sdp module (aka ib_sdp.ko) in the ofa_kernel package in the InfiniBand driver implementation in OpenFabrics Enterprise Distribution (OFED) before 1.5.3 does not properly handle certain non-array variables, which allows local users to cause a denial of service (stack memory corruption and system crash) by reading the /proc/net/sdpstats file.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
