The existing kfree() on hci_cmd_sync_queue\nfailure does not cover this path.","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-401"],"references":["https://git.kernel.org/stable/c/488e808e3fa53200f3ef3324c45fcba4ae9f4972","https://git.kernel.org/stable/c/a59d4f4217e6200ca9180643e5738a87d3fa8be0","https://git.kernel.org/stable/c/bfa9d28960ed677d556bdf097073bc3129686229","https://git.kernel.org/stable/c/e6b78019664dfe37c3dc707f50e7b453d6c7726d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-53364","score":0.0012,"percentile":0.01841,"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).
