CVE-2023-2194

kernel: i2c: out-of-bounds write in xgene_slimpro_i2c_xfer()

Published Apr 20, 2023 CVSS 3.1 · 6.7 Medium EPSS < 1% KEV · Not listed
Description
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.
