{"apiVersion":"1.0","identifier":"CVE-2026-72035","description":"In the Linux kernel, the following vulnerability has been resolved: net/sched: sch_taprio: Replace direct dequeue call with peek and qdisc_dequeue_peeked When taprio-s software path peeks a non-work-conserving child qdisc, the child stashes the peeked skb in its gso_skb; taprio_dequeue_from_txq() then takes the packet with a direct child ->dequeue() call, which ignores that stash, orphans the peeked skb and desyncs the child-s qlen/backlog. With a qfq child this re-enters the child on an emptied list and dereferences NULL, panicking the kernel from softirq on ordinary egress. Take the packet through qdisc_dequeue_peeked(), as sch_red and sch_sfb now do. The helper returns the child-s stashed skb first and is a no-op when there is none, so a work-conserving child is unaffected and the gated path now consumes the skb whose length was charged to the budget.","publishedAt":"2026-08-15T06:21:12","lastModifiedAt":"2026-08-23T13:16:37","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72035","cvssScore":8.2,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","epssProbability":0.00573,"riskScore":0.86,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72035","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72035","en":"https://www.redsauce.net/en/cves/CVE-2026-72035","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72035","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72035","de":"https://www.redsauce.net/de/cves/CVE-2026-72035","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72035","el":"https://www.redsauce.net/el/cves/CVE-2026-72035"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72035"}}
