"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Avoid NULL return from hist_field_name() on truncation\n\nhist_field_name() returns \"\" everywhere except the fully-qualified\nVAR_REF/EXPR case, where snprintf() truncation returns NULL early\nand bypasses the bottom NULL->\"\" guard. Callers don't expect NULL:\nstrcat(expr, hist_field_name(field, 0)) at trace_events_hist.c:1758\nand the strcmp() in the sort-key match loop at :4804 both deref it.\n\nsystem and event_name are bounded by MAX_EVENT_NAME_LEN, but the\nfield name on a VAR_REF is kstrdup'd from a histogram variable\nname parsed out of the trigger string and has no length cap, so\na long enough var name in a fully qualified reference can reach\nthe truncation path.\n\nKeep the length check but leave field_name as \"\" on overflow."
