一、漏洞信息
漏洞编号：CVE-2023-2194
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8
CVSS V3.0分值：
BaseScore：6.7 Medium
Vector：CVSS：3.0/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
An out-of-bounds write vulnerability was found in the Linux kernel s SLIMpro I2C device driver. The userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to crash the system or potentially achieve code execution.

CVE-2023-2194
I6XHPL
影响性分析说明：
An out-of-bounds write vulnerability was found in the Linux kernel s SLIMpro I2C device driver.
The userspace data->block[0] variable was not capped to a number between 0-255 and was used
as the size of a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a
local privileged user to crash the system or potentially achieve code execution.
