NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Rocky-Linux.
See How to fix? for Rocky-Linux:8 relevant fixed versions and status.
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.
