Description
In the Linux kernel, the following vulnerability has been resolved: Input: ti_am335x_tsc - fix off-by-one error in wire_order validation The current validation 'wire_order[i] > ARRAY_SIZE(config_pins)' allows wire_order[i] to equal ARRAY_SIZE(config_pins), which causes out-of-bounds access when used as index in 'config_pins[wire_order[i]]'. Since config_pins has 4 elements (indices 0-3), the valid range for wire_order should be 0-3. Fix the off-by-one error by using >= instead of > in the validation check.

Executive Summary

This vulnerability is an off-by-one error in the Linux kernel's ti_am335x_tsc input driver. The validation check for the wire_order array allows an index equal to the size of the config_pins array, which has 4 elements (indices 0-3). This causes an out-of-bounds access when the invalid index is used to access config_pins, potentially leading to unexpected behavior or crashes. The fix changes the validation to prevent wire_order indices from being equal to or greater than the array size.

Impact Analysis

The out-of-bounds access caused by the off-by-one error can lead to memory corruption, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or cause denial of service depending on the context in which the vulnerable code is used.
