Immediately after this, the code\naccesses nvec->rx->data[0] to check the message type.\n\nSince nvec_msg_free() marks the pool slot as available via atomic_set(),\nany concurrent or subsequent call to nvec_msg_alloc() could claim that\nsame slot and overwrite its data[] array. Reading nvec->rx->data[0] after\nfreeing the message is therefore a use-after-free.\n\nFix this by saving the message type byte before calling nvec_msg_free(),\nthen using the saved value for the battery quirk check.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.4},"cwes":[],"references":["https://git.kernel.org/stable/c/08626fcfe12308ca3f8b22c538ba7dee0b2dce7a","https://git.kernel.org/stable/c/26813881181deb3a32fbb59eadb2599cbe8423f6","https://git.kernel.org/stable/c/5de04caa46b635e180cecbd164e333eca535db94","https://git.kernel.org/stable/c/6b2ea886ebdae44a2394029844a4e78f58e1587d","https://git.kernel.org/stable/c/9f7fe4165a1f1014bdadc8e744c0fd3c2d8c0b89"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72489","score":0.0019,"percentile":0.08711,"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).
