Description

In the Linux kernel, the following vulnerability has been resolved: iio: health: afe4403: Fix oob read in afe4403_read_raw KASAN report out-of-bounds read as follows: BUG: KASAN: global-out-of-bounds in afe4403_read_raw+0x42e/0x4c0 Read of size 4 at addr ffffffffc02ac638 by task cat/279 Call Trace: afe4403_read_raw iio_read_channel_info dev_attr_show The buggy address belongs to the variable: afe4403_channel_leds+0x18/0xffffffffffffe9e0 This issue can be reproduced by singe command: $ cat /sys/bus/spi/devices/spi0.0/iio\:device0/in_intensity6_raw The array size of afe4403_channel_leds is less than channels, so access with chan->address cause OOB read in afe4403_read_raw.
