In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - zero report size on F54 work error In rmi_f54_work(), if an error occurs during report request or command verification, the code jumped directly to the 'error' label, bypassing the 'abort' label where f54->report_size was normally zeroed out. This left f54->report_size containing its previous successful payload size. If a user then altered the V4L2 format to a smaller size, and a subsequent run failed, rmi_f54_buffer_queue() would copy the stale, larger payload size into the shrunken V4L2 buffer, causing a heap buffer overflow. Fix this by merging the 'abort' and 'error' labels into a single 'out' exit path, and ensuring that f54->report_size is always set to 0 on failure by checking for error and zeroing the local report_size first.
