This could result in NULL pointer dereference when we only check\nsch->limit against sch->q.qlen.\n\nThis patch introduces a new helper, qdisc_dequeue_internal(), which ensures\nboth the gso_skb list and the main queue are properly flushed when trimming\nexcess packets. All relevant qdiscs (codel, fq, fq_codel, fq_pie, hhf, pie)\nare updated to use this helper in their ->change() routines.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://git.kernel.org/stable/c/2d3cbfd6d54a2c39ce3244f33f85c595844bd7b8","https://git.kernel.org/stable/c/a7d6e0ac0a8861f6b1027488062251a8e28150fd","https://git.kernel.org/stable/c/d1365ca80b012d8a7863e45949e413fb61fa4861","https://git.kernel.org/stable/c/d3336f746f196c6a53e0480923ae93939f047b6c","https://git.kernel.org/stable/c/d38939ebe0d992d581acb6885c1723fa83c1fb2c"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:57.636215869+00:00"},"epss":{"cve":"CVE-2025-37992","score":0.00217,"percentile":0.12238,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
