Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.3-rc3 (Operating System). This affects the function slimpro_i2c_blkwr of the file drivers/i2c/busses/i2c-xgene-slimpro.c of the component i2c. The manipulation with an unknown input leads to a out-of-bounds write vulnerability. CWE is classifying the issue as CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was presented 04/21/2023. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2023-2194 since 04/20/2023. Technical details are known, but no exploit is available.
