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":"2026-03-20T12:39:53.547408Z","published":"2024-12-27T14:50:51.781Z","related":["MGASA-2025-0030","MGASA-2025-0032","USN-7379-2","USN-7380-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56583.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0664e2c311b9fa43b33e3e81429cd0c2d7f9c638"},{"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":"b600d30402854415aa57548a6b53dc6478f65517"},{"fixed":"e41074904d9ed3fe582d6e544c77b40c22043c82"},{"fixed":"0664e2c311b9fa43b33e3e81429cd0c2d7f9c638"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"fd8cb2e71cdd8e814cbdadddd0d0e6e3d49eaa2c"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-56583.json"}}],"schema_version":"1.7.5"}
