{"apiVersion":"1.0","identifier":"CVE-2026-99269","description":"In the Linux kernel, the following vulnerability has been resolved: sched_ext: Wait for SCX_OPSS_DISPATCHING before moving tasks off DSQs A task can be found on a non-local DSQ while the CPU which dispatched it is still running ops.dequeue() and hasn-t cleared SCX_OPSS_DISPATCHING. The DSQ consume and move paths don-t wait for the dispatch to finish and can operate on the task concurrently with the dispatcher. Call scx_wait_dispatching() in scx_move_local_task_to_local_dsq(), unlink_dsq_and_switch_rq_lock() and move_task_between_dsqs() before they operate on the task. In scx_move_local_task_to_local_dsq(), wait before scx_resolve_local_dsq() as it may update p->scx.flags.","publishedAt":"2026-11-03T12:17:34","lastModifiedAt":"2026-11-03T20:18:32","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99269","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00146,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99269","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99269","en":"https://www.redsauce.net/en/cves/CVE-2026-99269","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99269","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99269","de":"https://www.redsauce.net/de/cves/CVE-2026-99269","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99269","el":"https://www.redsauce.net/el/cves/CVE-2026-99269"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99269"}}
