  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nInput: synaptics-rmi4 - zero report size on F54 work error\n\nIn rmi_f54_work(), if an error occurs during report request or command\nverification, the code jumped directly to the 'error' label, bypassing\nthe 'abort' label where f54-\u003ereport_size was normally zeroed out.\n\nThis left f54-\u003ereport_size containing its previous successful payload\nsize. If a user then altered the V4L2 format to a smaller size, and a\nsubsequent run failed, rmi_f54_buffer_queue() would copy the stale,\nlarger payload size into the shrunken V4L2 buffer, causing a heap\nbuffer overflow.\n\nFix this by merging the 'abort' and 'error' labels into a single 'out'\nexit path, and ensuring that f54-\u003ereport_size is always set to 0 on\nfailure by checking for error and zeroing the local report_size first.",
