Linux kernel Tehuti network buffer overflow

linux-kernel-tehuti-bo (42132) The risk level is classified as HighHigh Risk

Description:

Linux kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the Tehuti network driver. By sending a specially-crafted BDX_OP_WRITE IOCTL call, a local attacker could overflow a buffer to corrupt kernel memory and execute arbitrary code on the system or cause the system to crash.
