Linux Kernel CA-driver buffer overflow
| linux-kernel-cadriver-bo (43323) |  High Risk |
Description:
Linux Kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the CA-driver for the TwinHan DST Frontend/Card. By reading overly long bytes into an array, a local attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
