If the task is boosted, the warning\nis triggered. A boosted task already had its parameters set by\nrt_mutex_setprio, and a new call to setup_new_dl_entity is unnecessary,\nhence the WARN_ON call.\n\nCheck if we are requeueing a boosted task and avoid calling\nsetup_new_dl_entity if that's the case.","modified":"2026-11-07T02:31:11.226620524Z","published":"2024-12-27T14:50:51.781Z","related":["USN-7379-2","USN-7380-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56583.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0664e2c311b9fa43b33e3e81429cd0c2d7f9c638"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6923c1b117a93477c392a1d46da73ef40987a091"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b600d30402854415aa57548a6b53dc6478f65517"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e41074904d9ed3fe582d6e544c77b40c22043c82"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56583.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-56583"},{"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":"295d6d5e373607729bcc8182c25afe964655714f"},{"fixed":"6923c1b117a93477c392a1d46da73ef40987a091"},{"fixed":"b600d30402854415aa57548a6b53dc6478f65517"},{"fixed":"e41074904d9ed3fe582d6e544c77b40c22043c82"},{"fixed":"0664e2c311b9fa43b33e3e81429cd0c2d7f9c638"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.14.70"},{"fixed":"4.15"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"fd8cb2e71cdd8e814cbdadddd0d0e6e3d49eaa2c"}]}],"versions":["v4.14.336","v4.14.335","v4.14.334","v4.14.333","v4.14.332","v4.14.331","v4.14.330","v4.14.329","v4.14.328","v4.14.327","v4.14.326","v4.14.325","v4.14.324","v4.14.323","v4.14.322","v4.14.321","v4.14.320","v4.14.319","v4.14.318","v4.14.317","v4.14.316","v4.14.315","v4.14.314","v4.14.313","v4.14.312","v4.14.311","v4.14.310","v4.14.309","v4.14.308","v4.14.307","v4.14.306","v4.14.305","v4.14.304","v4.14.303","v4.14.302","v4.14.301","v4.14.300","v4.14.299","v4.14.298","v4.14.297","v4.14.296","v4.14.295","v4.14.294","v4.14.293","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","v4.14.123","v4.14.122","v4.14.121","v4.14.120","v4.14.119","v4.14.118","v4.14.117","v4.14.116","v4.14.115","v4.14.114","v4.14.113","v4.14.112","v4.14.111","v4.14.110","v4.14.109","v4.14.108","v4.14.107","v4.14.106","v4.14.105","v4.14.104","v4.14.103","v4.14.102","v4.14.101","v4.14.100","v4.14.99","v4.14.98","v4.14.97","v4.14.96","v4.14.95","v4.14.94","v4.14.93","v4.14.92","v4.14.91","v4.14.90","v4.14.89","v4.14.88","v4.14.87","v4.14.86","v4.14.85","v4.14.84","v4.14.83","v4.14.82","v4.14.81","v4.14.80","v4.14.79","v4.14.78","v4.14.77","v4.14.76","v4.14.75","v4.14.74","v4.14.73","v4.14.72","v4.14.71","v4.14.70"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-56583.json"}},{"package":{"name":"Kernel","ecosystem":"
