{"id":"CVE-2025-37932","summary":"sch_htb: make htb_qlen_notify() idempotent","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsch_htb: make htb_qlen_notify() idempotent\n\nhtb_qlen_notify() always deactivates the HTB class and in fact could\ntrigger a warning if it is already deactivated. Therefore, it is not\nidempotent and not friendly to its callers, like fq_codel_dequeue().\n\nLet's make it idempotent to ease qdisc_tree_reduce_backlog() callers'\nlife.","modified":"2026-05-15T11:53:56.263260041Z","published":"2025-05-20T15:21:57.469Z","related":["SUSE-SU-2025:01964-1","SUSE-SU-2025:01965-1","SUSE-SU-2025:01983-1","SUSE-SU-2025:02000-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02264-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02308-1","SUSE-SU-2025:02320-1","SUSE-SU-2025:02321-1","SUSE-SU-2025:02322-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02537-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20408-1","SUSE-SU-2025:20413-1","SUSE-SU-2025:20419-1","SUSE-SU-2025:20421-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37932.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0a188c0e197383683fd093ab1ea6ce9a5869a6ea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/32ae12ce6a9f6bace186ca7335220ff59b6cc3cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ba8b837b522d7051ef81bacf3d95383ff8edce5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73cf6af13153d62f9b76eff422eea79dbc70f15e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/967955c9e57f8eebfccc298037d4aaf3d42bc1c9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a61f1b5921761fbaf166231418bc1db301e5bf59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbbf5e0f87078b715e7a665d662a2c0e77f044ae"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6b45f4de763b00dc1c55e685e2dd1aaf525d3c1"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/08/msg00010.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37932.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-37932"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.14.0"},{"fixed":"5.4.294"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.241"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.190"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.138"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.90"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.28"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.14.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-37932.json"}}],"schema_version":"1.7.5"}
