If the root qdisc do not implement the\nTCQ_F_DEQUEUE_DROPS flag the packets queue to free are never freed and\ngets stranded on the child's local to_free list.\n\nFix this by making qdisc_dequeue_drop() aware of the root qdisc. It\nfetches the root qdisc and check for the TCQ_F_DEQUEUE_DROPS flag. If\nthe flag is present, the packet is appended directly to the root's\nto_free list. Otherwise, drop it directly as it was done before the\noptimization was implemented.","published_at":"2026-06-24T16:30:20.163000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":null,"nvd_references":["https://git.kernel.org/stable/c/bf26ad92ffda7884825d67b46bd5efe615c3babf","https://git.kernel.org/stable/c/a6bd339dbb3514bce690fdcf252e788dfab4ee76"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:28.590503Z","updated_at":"2026-06-28T23:30:50.753831Z"},"effective_severity":null,"badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"a6efc273ab8245722eee2150fa12cf75781dc410","version_start_inclusive":true,"version_end":"bf26ad92ffda7884825d67b46bd5efe615c3babf","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:a6efc273ab8245722eee2150fa12cf75781dc410:bf26ad92ffda7884825d67b46bd5efe615c3babf"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"a6efc273ab8245722eee2150fa12cf75781dc410","version_start_inclusive":true,"version_end":"a6bd339dbb3514bce690fdcf252e788dfab4ee76","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:a6efc273ab8245722eee2150fa12cf75781dc410:a6bd339dbb3514bce690fdcf252e788dfab4ee76"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"6.19","version_start_inclusive":true,"version_end":"6.19","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:6.19:6.19"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"0","version_start_inclusive":true,"version_end":"6.19","version_end_inclusive":false,"cpe23_uri":"cve5:linux:linux:0:6.19"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.0.10","version_start_inclusive":true,"version_end":"7.0.*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.0.10:7.0.*"},{"vendor_slug":"linux","vendor_name":"Linux","product_slug":"linux","product_name":"Linux","version_start":"7.1","version_start_inclusive":true,"version_end":"*","version_end_inclusive":true,"cpe23_uri":"cve5:linux:linux:7.1:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://git.kernel.org/stable/c/bf26ad92ffda7884825d67b46bd5efe615c3babf","source_type":"MISC","tags":[]},{"url":"https://git.kernel.org/stable/c/a6bd339dbb3514bce690fdcf252e788dfab4ee76","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-24T16:30:20.163000Z","label":"CVE published","source":null}]}
