In the Linux kernel, the following vulnerability has been resolved: i2c: rtl9300: Fix out-of-bounds bug in rtl9300_i2c_smbus_xfer The data->block[0] variable comes from user. Without proper check, the variable may be very large to cause an out-of-bounds bug. Fix this bug by checking the value of data->block[0] first. 1. commit 39244cc75482 ("i2c: ismt: Fix an out-of-bounds bug in ismt_access()") 2. commit 92fbb6d1296f ("i2c: xgene-slimpro: Fix out-of-bounds bug in xgene_slimpro_i2c_xfer()")
