First published: Thu Apr 20 2023(Updated: )
An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The flaw lies in the xgene_slimpro_i2c_xfer() function. Quoting the upstream commit below: "The data->block[0] variable comes from user and is a number between 0-255. Without proper check, the variable may be very large to cause an out-of-bounds when performing memcpy in slimpro_i2c_blkwr."
