A patch is available and has been released by Ubuntu as part of security update USN-8096-1. Users should update their Linux kernel to the fixed versions listed in the advisory to remediate this vulnerability. The affected versions are prior to 5.15.0-1103.110~20.04.1, 5.15.0-1110.119~20.04.1, 5.15.0-1103.112~20.04.1, 5.15.0-173.183~20.04.1, and 5.15.0-1097.100~20.04.1. No additional mitigations are indicated by the vendor advisory.
Description
An off-by-one error in the Linux kernel's ti_am335x_tsc input driver allowed out-of-bounds access due to improper validation of the wire_order array index. The validation check permitted wire_order[i] to equal the size of the config_pins array, which has 4 elements, causing an out-of-bounds access when indexing config_pins. This vulnerability has been fixed by changing the validation condition to prevent wire_order[i] from being equal to or greater than the array size. The issue affects certain Linux kernel versions prior to specific 5.15.x updates.
