Once the value of length exceeds\nthe value of buflen in function smc_clc_wait_msg it may run into deadloop\nwhen trying to drain the remaining data exceeding buflen.\n\nThis patch checks the return value of sock_recvmsg when draining data in\ncase of deadloop in draining.","state":0,"publishedAt":"2025-01-11T12:35:48.905+00:00","modifiedAt":"2026-10-15T21:51:48.859+00:00","affected":[{"ecosystem":"Vendor
