{"id":"CVE-2022-49957","summary":"kcm: fix strp_init() order and cleanup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nkcm: fix strp_init() order and cleanup\n\nstrp_init() is called just a few lines above this csk-\u003esk_user_data\ncheck, it also initializes strp-\u003ework etc., therefore, it is\nunnecessary to call strp_done() to cancel the freshly initialized\nwork.\n\nAnd if sk_user_data is already used by KCM, psock-\u003estrp should not be\ntouched, particularly strp-\u003ework state, so we need to move strp_init()\nafter the csk-\u003esk_user_data check.\n\nThis also makes a lockdep warning reported by syzbot go away.","modified":"2026-10-28T02:30:41.588482691Z","published":"2025-06-18T11:00:19.238Z","related":["SUSE-SU-2025:02264-1","SUSE-SU-2025:02321-1","SUSE-SU-2025:02322-1","SUSE-SU-2025:02334-1","SUSE-SU-2025:02537-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49957.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0946ff31d1a8778787bf6708beb20f38715267cc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1b6666964ca1de93a7bf06e122bcf3616dbd33a9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/473f394953216614087f4179e55cdf0cf616a13b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/55fb8c3baa8071c5d533a9ad48624e44e2a04ef5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8fc29ff3910f3af08a7c40a75d436b5720efe2bf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a8a0c321319ad64a5427d6172cd9c23b4d6ca1e8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f865976baa85915c7672f351b74d5974b93215f6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49957.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49957"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"44890e9ff771ef11777b2d1ebf8589255eb12502"},{"fixed":"473f394953216614087f4179e55cdf0cf616a13b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e5571240236c5652f3e079b1d5866716a7ad819c"},{"fixed":"a8a0c321319ad64a5427d6172cd9c23b4d6ca1e8"},{"fixed":"0946ff31d1a8778787bf6708beb20f38715267cc"},{"fixed":"1b6666964ca1de93a7bf06e122bcf3616dbd33a9"},{"fixed":"55fb8c3baa8071c5d533a9ad48624e44e2a04ef5"},{"fixed":"f865976baa85915c7672f351b74d5974b93215f6"},{"fixed":"8fc29ff3910f3af08a7c40a75d436b5720efe2bf"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.14.22"},{"fixed":"4.14.293"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.9.84"},{"fixed":"4.10"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.9.100"},{"fixed":"4.10"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"085cbbda4b4cc7dd2ba63806346881c2c2e10107"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"383250363daf01eb7aa3728c09ef8a4f6d8a3252"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"19042316b9e12c93bf334a04d4dd7a4e846c7311"}]}],"versions":["v4.14.292","v4.14.291","v4.14.290","v4.14.289","v4.14.288","v4.14.287","v4.14.286","v4.14.285","v4.14.284","v4.14.283","v4.14.282","v4.14.281","v4.14.280","v4.14.279","v4.14.278","v4.14.277","v4.14.276","v4.14.275","v4.14.274","v4.14.273","v4.14.272","v4.14.271","v4.14.270","v4.14.269","v4.14.268","v4.14.267","v4.14.266","v4.14.265","v4.14.264","v4.14.263","v4.14.262","v4.14.261","v4.14.260","v4.14.259","v4.14.258","v4.14.257","v4.14.256","v4.14.255","v4.14.254","v4.14.253","v4.14.252","v4.14.251","v4.14.250","v4.14.249","v4.14.248","v4.14.247","v4.14.246","v4.14.245","v4.14.244","v4.14.243","v4.14.242","v4.14.241","v4.14.240","v4.14.239","v4.14.238","v4.14.237","v4.14.236","v4.14.235","v4.14.234","v4.14.233","v4.14.232","v4.14.231","v4.14.230","v4.14.229","v4.14.228","v4.14.227","v4.14.226","v4.14.225","v4.14.224","v4.14.223","v4.14.222","v4.14.221","v4.14.220","v4.14.219","v4.14.218","v4.14.217","v4.14.216","v4.14.215","v4.14.214","v4.14.213","v4.14.212","v4.14.211","v4.14.210","v4.14.209","v4.14.208","v4.14.207","v4.14.206","v4.14.205","v4.14.204","v4.14.203","v4.14.202","v4.14.201","v4.14.200","v4.14.199","v4.14.198","v4.14.197","v4.14.196","v4.14.195","v4.14.194","v4.14.193","v4.14.192","v4.14.191","v4.14.190","v4.14.189","v4.14.188","v4.14.187","v4.14.186","v4.14.185","v4.14.184","v4.14.183","v4.14.182","v4.14.181","v4.14.180","v4.14.179","v4.14.178","v4.14.177","v4.14.176","v4.14.175","v4.14.174","v4.14.173","v4.14.172","v4.14.171","v4.14.170","v4.14.169","v4.14.168","v4.14.167","v4.14.166","v4.14.165","v4.14.164","v4.14.163","v4.14.162","v4.14.161","v4.14.160","v4.14.159","v4.14.158","v4.14.157","v4.14.156","v4.14.155","v4.14.154","v4.14.153","v4.14.152","v4.14.151","v4.14.150","v4.14.149","v4.14.148","v4.14.147","v4.14.146","v4.14.145","v4.14.144","v4.14.143","v4.14.142","v4.14.141","v4.14.140","v4.14.139","v4.14.138","v4.14.137","v4.14.136","v4.14.135","v4.14.134","v4.14.133","v4.14.132","v4.14.131","v4.14.130","v4.14.129","v4.14.128","v4.14.127","v4.14.126","v4.14.125","v4.14.124","v4.14
