CVE-2022-49957

CVE-2022-49957 concerns a Linux kernel issue in the kcm path where strp_init() is invoked before the csk->sk_user_data check. The vulnerability arises because strp_init() initializes strp->work (and others); calling strp_done() to cancel it is unnecessary if sk_user_data isn’t checked yet. ...
